----
-
-# Open Match Release Process
-
-Follow these instructions to create an Open Match release. The output of the
-release process is new images and new configuration.
-
-## Getting setup
-
-**NOTE: The instructions below are NOT strictly copy-pastable and assume 0.5**
-**release. Please update the version number for your commands.**
-
-The Git flow for pushing a new release is similar to the development process
-but there are some small differences.
-
-### 1. Clone Repository
-
-```shell
-# Clone your fork of the Open Match repository.
-git clone git@github.com:afeddersen/open-match.git
-# Change directory to the git repository.
-cd open-match
-# Add a remote, you'll be pushing to this.
-git remote add upstream https://github.com/googleforgames/open-match.git
-```
-
-### 2. Release Branch
-
-If you're creating the first release of the version, that would be `0.5.0-rc.1`
-then you'll need to create the release branch.
-
-```shell
-# Create a local release branch.
-git checkout -b release-0.5 upstream/master
-# Push the branch upstream.
-git push upstream release-0.5
-```
-
-otherwise there should already be a `release-0.5` branch so run,
-
-```shell
-# Checkout the release branch.
-git checkout -b release-0.5 upstream/release-0.5
-```
-
-**NOTE: The branch name must be in the format, `release-X.Y` otherwise**
-**some artifacts will not be pushed.**
-
-## Releases & Versions
-
-Open Match uses Semantic Versioning 2.0.0. If you're not familiar please
-see the documentation - [https://semver.org/](https://semver.org/).
-
-Full Release / Stable Release:
-
-* The final software product. Stable, reliable, etc...
-* Example: 1.0.0, 1.1.0
-
-Release Candidate (RC):
-
-* A release candidate (RC) is a version with the potential to be the final
-  product but it hasn't validated by automated and/or manual tests.
-* Example: 1.0.0-rc.1
-
-Hot Fixes:
-
-* Code developed to correct a major software bug or fault
-  that's been discovered after the full release.
-* Example: 1.0.1
-
-Preview:
-
-* Rare, a one off release cut from the master branch to provide early access
-  to APIs or some other major change.
-* **NOTE: There's no branch for this release.** 
-* Example: 0.5-preview.1
-
-**NOTE: Semantic versioning is enforced by `go mod`. A non-compliant version**
-**tag will cause `go get` to break for users.**
-
-# Detailed Instructions
-
-## Find and replace
-
-Below this point you will see {version} used as a placeholder for future
-releases. Find {version} and replace with the current release (e.g. 0.5.0)
-
-## Create a release branch in the upstream open-match repository
-
-**Note: This step is performed by the person who starts the release.  It is
-only required once.**
-
-- [ ] Create the branch in the **upstream** repository. It should be named
-  release-X.Y. Example: release-0.5. At this point there's effectively a code
-  freeze for this version and all work on master will be included in a future
-  version. If you're on the branch that you created in the *getting setup*
-  section above you should be able to push upstream.
-
-```shell
-git push origin release-0.5
-```
-
-- [ ] Announce a PR freeze on release-X.Y branch on [open-match-discuss@](mailing-list-post).
-- [ ] Open the [`Makefile`](makefile-version) and change BASE_VERSION entry.
-- [ ] Open the [`install/helm/open-match/Chart.yaml`](om-chart-yaml-version) and change the `appVersion` and `version` entries.
-- [ ] Open the [`install/helm/open-match/values.yaml`](om-values-yaml-version) and change the `tag` entries.
-- [ ] Open the [`cloudbuild.yaml`] and change the `_OM_VERSION` entry.
-- [ ] There might be additional references to the old version but be careful not to change it for places that have it for historical purposes.
-- [ ] Run `make release`
-- [ ] Run `make api/api.md` in open-match repo to update the auto-generated API references in open-match-docs repo.
-- [ ] Use the files under the `build/release/` directory for the Open Match installation guide. Make sure the artifacts work as expected - these are the artifacts that will be published to the GCS bucket and used in our release assets.
-- [ ] Create a PR with the changes, include the release candidate name, and point it to the release branch.
-- [ ] Go to [open-match-build](https://pantheon.corp.google.com/cloud-build/triggers?project=open-match-build) and update all *post submit* triggers' `_GCB_LATEST_VERSION` value to the `X.Y` of the release. This value should only increase as it's used to determine the latest stable version.
-- [ ] Merge your changes once the PR is approved.
-
-## Create a release branch in the upstream open-match-docs repository
-- [ ] Open [`Makefile`](makefile-version) and change BASE_VERSION entry.
-- [ ] Open [`cloudbuild.yaml`] and change the `_OM_VERSION` entry.
-- [ ] Open [`site/config.toml`] and change the `release_version` entry.
-- [ ] Open [`site/static/swaggerui/config.json`] and change the `api/VERSION/...` entries
-- [ ] Create a PR with the changes, include the release candidate name, and point it to the release branch.
-
-## Complete Milestone
-
-**Note: This step is performed by the person who starts the release. It is
-only required once.**
-- [ ] Create the next [version milestone](https://github.com/googleforgames/open-match/milestones) and use [semantic versioning](https://semver.org/) when naming it to be consistent with the [Go community](https://blog.golang.org/versioning-proposal).
-- [ ] Create a *draft* [release](https://github.com/googleforgames/open-match/releases).  Note that github has both "Pre-release" and "draft" as different concepts for a release.  Until the release is finalized, only use "Save draft", and do not use "Publish release".
-- [ ] Use the [release template](https://github.com/googleforgames/open-match/blob/master/docs/governance/templates/release.md)
-  - [ ] `Tag` = v{version}. Example: v0.5.0. Append -rc.# for release candidates. Example: v0.5.0-rc.1.
-  - [ ] `Target` = release-X.Y. Example: release-0.5.
-  - [ ] `Release Title` = `Tag`
-  - [ ] `Write` section will contain the contents from the [release template](https://github.com/googleforgames/open-match/blob/master/docs/governance/templates/release.md).
-- [ ] Add the milestone to all PRs and issues that were merged since the last milestone. Look at the [releases page](https://github.com/googleforgames/open-match/releases) and look for the "X commits to master since this release" for the diff.
-- [ ] Review all [milestone-less closed issues](https://github.com/googleforgames/open-match/issues?q=is%3Aissue+is%3Aclosed+no%3Amilestone) and assign the appropriate milestone.
-- [ ] Review all [issues in milestone](https://github.com/googleforgames/open-match/milestones) for proper [labels](https://github.com/googleforgames/open-match/labels) (ex: area/build).
-- [ ] Review all [milestone-less closed PRs](https://github.com/googleforgames/open-match/pulls?q=is%3Apr+is%3Aclosed+no%3Amilestone) and assign the appropriate milestone.
-- [ ] Review all [PRs in milestone](https://github.com/googleforgames/open-match/milestones) for proper [labels](https://github.com/googleforgames/open-match/labels) (ex: area/build).
-- [ ] View all open entries in milestone and move them to a future milestone if they aren't getting closed in time. https://github.com/googleforgames/open-match/milestones/v{version}
-- [ ] Review all closed PRs against the milestone. Put the user visible changes into the release notes using the suggested format. https://github.com/googleforgames/open-match/pulls?utf8=%E2%9C%93&q=is%3Apr+is%3Aclosed+is%3Amerged+milestone%3Av{version}
-- [ ] Review all closed issues against the milestone. Put the user visible changes into the release notes using the suggested format. https://github.com/googleforgames/open-match/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aclosed+milestone%3Av{version}
-- [ ] Verify the [milestone](https://github.com/googleforgames/open-match/milestones) is effectively 100% at this point with the exception of the release issue itself.
-
-## Build Artifacts
-
-- [ ] Go to the History section and find the "Post Submit" build of the merged commit that's running. Wait for it to go Green. If it's red, fix error repeat this section. Take note of the docker image version tag for next step. Example: 0.5.0-a4706cb.
-- [ ] Run `./docs/governance/templates/release.sh {source version tag} {version}` to copy the images to open-match-public-images.
-- [ ] If this is a new minor version in the newest major version then run `./docs/governance/templates/release.sh {source version tag} latest`.
-- [ ] Copy the files from `build/release/` generated from `make release` to the release draft you created.  You can drag and drop the files using the Github UI.
-- [ ] Update [Slack invitation link](https://slack.com/help/articles/201330256-invite-new-members-to-your-workspace#share-an-invite-link) in [open-match.dev](https://open-match.dev/site/docs/contribute/#get-involved).
-- [ ] Test Open Match installation under GKE and Minikube enviroment using YAML files and Helm. Follow the [First Match](https://development.open-match.dev/site/docs/getting-started/first_match/) guide, run `make proxy-demo`, and open `localhost:51507` to make sure everything works.
-  - [ ] Minikube: Run `make create-mini-cluster` to create a local cluster with latest Kubernetes API version.
-  - [ ] GKE: Run `make create-gke-cluster` to create a GKE cluster.
-  - [ ] Helm: Run `helm install open-match -n open-match open-match/open-match`
-- [ ] Update usage requirements in the Installation doc - e.g. supported minikube version, kubectl version, golang version, etc.
-
-## Finalize
-
-- [ ] Save the release as a draft.
-- [ ] Circulate the draft release to active contributors.  Where reasonable, get everyone's ok on the release notes before continuing.
-- [ ] Publish the [Release](om-release) in Github.  This will notify repository watchers.
-
-## Announce
-
-- [ ] Send an email to the [mailing list](mailing-list-post) with the release details (copy-paste the release blog post)
-- [ ] Send a chat on the [Slack channel](om-slack). "Open Match {version} has been released! Check it out at {release url}."

+
+## v0.4.0 (alpha)
+
+### Release notes
+- Thanks to completion of Issues [#42](issues/42) and [#45](issues/45), there is no longer a need to use the `openmatch-base` image when building components of Open Match.  Each stand alone appliation now is self-contained in its `Dockerfile` and `cloudbuild.yaml` files, and builds have been substantially simplified.  **Note**: The default `Dockerfile` and `cloudbuild.yaml` now tag their images with the version number, not `dev`, and the YAML files in the `install` directory now reflect this.
+ - This paves the way for CI/CD in an upcoming version.  
+ - This paves the way for public images in an upcoming version!
+
+## v0.3.0 (alpha)
+  This update is focused on the Frontend API and Player Records, including more robust code for indexing, deindexing, reading, writing, and expiring player requests from Open Match state storage.  All Frontend API function argument have changed, although many only slightly. Please join the [Slack channel](https://open-match.slack.com/) if you need help ([Signup link](https://join.slack.com/t/open-match/shared_invite/enQtNDM1NjcxNTY4MTgzLWQzMzE1MGY5YmYyYWY3ZjE2MjNjZTdmYmQ1ZTQzMmNiNGViYmQyN2M4ZmVkMDY2YzZlOTUwMTYwMzI1Y2I2MjU))!
+
+### Release notes
+- The Frontend API calls have all be changed to reflect the fact that they operate on Players in state storage.  To queue a game client, 'CreatePlayer' in Open Match, to get updates 'GetUpdates', and to stop matching, 'DeletePlayer'. The calls are now much more obviously related to how Open Match sees players: they are database records that it creates on demand, updates using MMFs and the Backend API, and deletes when the player is no longer looking for a match.  
+- The Player record in state storage has changed to a more complete hash format, and it no longer makes sense to remove a player's assignment from the Frontend as a separate action to removing their record entirely.  `DeleteAssignment()` has therefore been removed.  Just use `DeletePlayer` instead; you'll always want the client to re-request matching with its latest attributes anyway.
+- There is now a module for [indexing and deindexing players in state storage](internal/statestorage/redis/playerindices/playerindices.go).  This is a *much* more efficient, as well as being cleaner and more maintainable than the previous implementation which was **hard-coded to index everything** you passed in to the Frontend API at a specific JSON object depth.
+    - This paves the way for dynamically choosing your indicies without restarting the matchmaker.  This will be implemented if there is demand.  Pull Requests are welcome!
+    - Two internal timestamp-based indices have replaced the previous `timestamp` index. `created` is used to calculate how long a player has been waiting for a match, `accessed` is used to determine when a player needs to be expired out of state storage.  Both are prefixed by the string `OM_METADATA` so it should be easy to spot them.
+- A call to the Frontend API `GetUpdates()` gRPC endpoint returns a stream of player messages. This is used to send updates to state storage for the `Assignment`, `Status`, and `Error` Player fields in near-realtime. **It is the responsibility of the game client to disconnect** from the stream when it has gotten the results it was waiting for!
+- Moved the rest of the gRPC messages into a shared [`messages.proto` file](api/protobuf-spec/messages.proto).
+- Added documentation to Frontend API gRPC calls to the [`frontend.proto` file](api/protobuf-spec/frontend.proto).
+- [Issue #41](https://github.com/GoogleCloudPlatform/open-match/issues/41)|[PR #48](https://github.com/GoogleCloudPlatform/open-match/pull/48) There is now a HA Redis install available in `install/yaml/01-redis-failover.yaml`.  This would be used as a drop-in replacement for a single-instance Redis configuration in `install/yaml/01-redis.yaml`.  The HA configuration requires that you install the [Redis Operator](https://github.com/spotahome/redis-operator) (note: **currently alpha**, use at your own risk) in your Kubernetes cluster.
+    - As part of this change, the kubernetes service name is now `redis` not `redis-sentinel` to denote that it is accessed using a standard Redis client.
+- Open Match uses a new feature of the go module [logrus](github.com/sirupsen/logrus) to include filenames and line numbers.  If you have an older version in your local build environment, you may need to delete the module and `go get github.com/sirupsen/logrus` again.  When building using the provided `cloudbuild.yaml` and `Dockerfile`s this is handled for you.
+- The program that was formerly in `examples/frontendclient` has been expanded and has been moved to the `test` directory under (`test/cmd/frontendclient/`)[test/cmd/frontendclient/].
+- The client load generator program has been moved from `test/cmd/client` to (`test/cmd/clientloadgen/`)[test/cmd/clientloadgen/] to better reflect what it does.
+- [Issue #45](https://github.com/GoogleCloudPlatform/open-match/issues/45) The process for moving the build files (`Dockerfile` and `cloudbuild.yaml`) for each component, example, and test program to their respective directories and out of the repository root has started but won't be completed until a future version.
+- Put some basic notes in the [production guide](docs/production.md)
+- Added a basic [roadmap](docs/roadmap.md)
+
+## v0.2.0 (alpha)
+  This is a pretty large update.  Custom MMFs or evaluators from 0.1.0 may need some tweaking to work with this version. Some Backend API function arguments have changed. Please join the [Slack channel](https://open-match.slack.com/) if you need help ([Signup link](https://join.slack.com/t/open-match/shared_invite/enQtNDM1NjcxNTY4MTgzLWQzMzE1MGY5YmYyYWY3ZjE2MjNjZTdmYmQ1ZTQzMmNiNGViYmQyN2M4ZmVkMDY2YzZlOTUwMTYwMzI1Y2I2MjU))!
+
+  v0.2.0 focused on adding additional functionality to Backend API calls and on **reducing the amount of boilerplate code required to make a custom Matchmaking Function**.  For this, a new internal API for use by MMFs called the [Matchmaking Logic API (MMLogic API)](README.md#matchmaking-logic-mmlogic-api) has been added.  Many of the core components and examples had to be updated to use the new Backend API arguments and the modules to support them, so we recommend you rebuild and redeploy all the components to use v0.2.0. 
+
+### Release notes
+- MMLogic API is now available.  Deploy it to kubernetes using the [appropriate json file]() and check out the [gRPC API specification](api/protobuf-spec/mmlogic.proto) to see how to use it.  To write a client against this API, you'll need to compile the protobuf files to your language of choice. There is an associated cloudbuild.yaml file and Dockerfile for it in the root directory.
+    - When using the MMLogic API to filter players into pools, it will attempt to report back the number of players that matched the filters and how long the filters took to query state storage.
+    - An [example MMF](examples/functions/python3/mmlogic-simple/harness.py) using it has been written in Python3. There is an associated cloudbuild.yaml file and Dockerfile for it in the root directory. By default the [example backend client](examples/backendclient/main.go) is now configured to use this MMF, so make sure you have it avaiable before you try to run the latest backend client.
+    - An [example MMF](examples/functions/php/mmlogic-simple/harness.py) using it has been contributed by Ilya Hrankouski in PHP (thanks!).   - The API specs have been split into separate files per API and the protobuf messages are in a separate file.  Things were renamed slightly as a result, and you will need to update your API clients. The Frontend API hasn't had it's messages moved to the shared messages file yet, but this will happen in an upcoming version.
+    - The [example golang MMF](examples/functions/golang/manual-simple/) has been updated to use the latest data schemas for MatchObjects, and renamed to `manual-simple` to denote that it is manually manipulating Redis, not using the MMLogic API.
+    - The API specs have been split into separate files per API and the protobuf messages are in a separate file.  Things were renamed slightly as a result, and you will need to update your API clients. The Frontend API hasn't had it's messages moved to the shared messages file yet, but this will happen in an upcoming version.
+- The message model for using the Backend API has changed slightly - for calls that make MatchObjects, the expectation is that you will provide a MatchObject with a few fields populated, and it will then be shuttled along through state storage to your MMF and back out again, with various processes 'filling in the blanks' of your MatchObject, which is then returned to your code calling the Backend API.  Read the[gRPC API specification](api/protobuf-spec/backend.proto) for more information.
+    - As part of this, compiled protobuf golang modules now live in the [`internal/pb`](internal/pb) directory.  There's a handy [bash script](api/protoc-go.sh) for compiling them from the `api/protobuf-spec` directory into this new `internal/pb` directory for development in your local golang environment if you need it.  
+    - As part of this Backend API message shift and the advent of the MMLogic API, 'player pools' and 'rosters' are now first-class data structures in MatchObjects for those who wish to use them. You can ignore them if you like, but if you want to use some of the MMLogic API calls to automate tasks for you - things like filtering a pool of players according attributes or adding all the players in your rosters to the ignorelist so other MMFs don't try to grab them - you'll need to put your data into the [protobuf messages](api/protobuf-spec/messages.proto) so Open Match knows how to read them.  The sample backend client [test profile JSON](examples/backendclient/profiles/testprofile.json)has been updated to use this format if you want to see an example.
+- Rosters were formerly space-delimited lists of player IDs.  They are now first-class repeated protobuf message fields in the [Roster message format](api/protobuf-spec/messages.proto). That means that in most languages, you can access the roster as a list of players using your native language data structures (more info can be found in the [guide for using protocol buffers in your langauge of choice](https://developers.google.com/protocol-buffers/docs/reference/overview)).  If you don't care about the new fields or the new functionality, you can just leave all the other fields but the player ID unset.
+ - Open Match is transitioning to using [protocol buffer messages](https://developers.google.com/protocol-buffers/) as its internal data format. There is now a Redis state storage [golang module](internal/statestorage/redis/redispb/) for marshaling and unmarshaling MatchObject messages to and from Redis. It isn't very clean code right now but will get worked on for the next couple releases.
+ - Ignorelists now exist, and have a Redis state storage [golang module](internal/statestorage/redis/ignorelist/) for CRUD access.  Currently three ignorelists are defined in the [config file](config/matchmaker_config.json) with their respective parameters. These are implemented as [Sorted Sets in Redis](https://redis.io/commands#sorted_set).
+ - For those who only want to stand up Open Match and aren't interested in individually tweaking the required kubernetes resources, there are now [three YAML files](install/yaml) that can be used to install Redis, install Open Match, and (optionally) install Prometheus. You'll still need the `sed` [instructions from the Developer Guide](docs/development.md#running-open-match-in-a-development-environment) to substitute in the name of your Docker container registry.
+ - A super-simple module has been created for doing instersections, unions, and differences of lists of player IDs.  It lives in `internal/set/set.go`.  
+
+
+### Roadmap 
+- It has become clear from talking to multiple users that the software they write to talk to the Backend API needs a name.  'Backend API Client' is technically correct, but given how many APIs are in Open Match and the overwhelming use of 'Client' to refer to a Game Client in the industry, we're currently calling this a 'Director', as its primary purpose is to 'direct' which profiles are sent to the backend, and 'direct' the resulting MatchObjects to game servers.  Further discussion / suggestions are welcome.
+- We'll be entering the design stage on longer-running MMFs before the end of the year. We'll get a proposal together and on the github repo as a request for comments, so please keep your eye out for that.
+- Match profiles providing multiple MMFs to run isn't planned anymore.  Just send multiple copies of the profile with different MMFs specified via the backendapi. 
+- Redis Sentinel will likely not be supported.  Instead, replicated instances and HAProxy may be the HA solution of choice. There's an [outstanding issue to investigate and implement](https://github.com/GoogleCloudPlatform/open-match/issues/41) if it fills our needs, feel free to contribute!

-Open Match is an open source game matchmaking framework that simplifies building
-a scalable and extensible Matchmaker. It is designed to give the game developer
-full control over how to make matches while removing the burden of dealing with
-the challenges of running a production service at scale.
+Open Match is an open source game matchmaking framework designed to allow game creators to build matchmakers of any size easily and with as much possibility for sharing and code re-use as possible. It’s designed to be flexible, extensible, and scalable.
 
-Please visit [Open Match website](https://open-match.dev/site/docs/) for user
-documentation, demo instructions etc.
+Matchmaking begins when a player tells the game that they want to play. Every player has a set of attributes like skill, location, playtime, win-lose ratio, etc which may factor in how they are paired with other players. Typically, there's a trade off between the quality of the match vs the time to wait. Since Open Match is designed to scale with the player population, it should be possible to still have high quality matches while having high player count.
 
-## Contributing to Open Match
+Under the covers matchmaking approaches touch on significant areas of computer science including graph theory and massively concurrent processing. Open Match is an effort to provide a foundation upon which these difficult problems can be addressed by the wider game development community. As Josh Menke — famous for working on matchmaking for many popular triple-A franchises — put it:
 
-Open Match is in active development and we would love your contribution! Please
-read the [contributing guide](CONTRIBUTING.md) for guidelines on contributing to
-Open Match.
+["Matchmaking, a lot of it actually really is just really good engineering. There's a lot of really hard networking and plumbing problems that need to be solved, depending on the size of your audience."](https://youtu.be/-pglxege-gU?t=830)
 
-The [Open Match Development guide](docs/development.md) has detailed instructions
-on getting the source code, making changes, testing and submitting a pull request
-to Open Match.
+This project attempts to solve the networking and plumbing problems, so game developers can focus on the logic to match players into great games.
+
+## Open Match Demo
+
+This section lists the steps to set up a demo for the basic functionality of Open Match. If you just want to see an E2E Open Match setup in action, please continue with this section. If you want to build Open Match from source, or modify the match functions, please follow the [Development Guide](docs/development.md).
+
+### Create a Kubernetes Cluster
+
+Open Match framework is a collection of servers that run within a Kubernetes cluster. Having a Kubernetes cluster is a prerequisite to deploying Open Match. If you want to deploy Open Match to an existing Kubernetes cluster, skip this step and proceed to Deploying Open Match, otherwise create a kubernetes cluster with one of the options listed below:
+
+* [Set up a Google Cloud Kubernetes Cluster](docs/gcloud.md) (*this may involve extra charges unless you are on free tier*)
+* [Set up a Local Minikube cluster](https://kubernetes.io/docs/setup/minikube/)
+
+### Deplying Open Match
+
+Run the following steps to deploy core Open Match components and the monitoring services in the Kubernetes cluster.
+
+```bash
+# Create a cluster role binding (if using gcloud)
+kubectl create clusterrolebinding cluster-admin-binding --clusterrole cluster-admin --user `gcloud config get-value account`
+
+# Create a cluster role binding (if using minikube)
+kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin --serviceaccount=kube-system:default
+
+# Create a namespace to place all the Open Match components in.
+kubectl create namespace open-match
+
+# Install the core Open Match and monitoring services.
+kubectl apply -f https://github.com/GoogleCloudPlatform/open-match/releases/download/0.5.0-rc.2/install.yaml --namespace open-match
+```
+
+### Deploy demo components
+
+Open Match framework requires the user to author a custom match function and an evaluator that are invoked to create matches. For demo purposes, we will use an example MMF and Evaluator. The following command deploys these in the kubernetes cluster:
+
+```bash
+kubectl apply -f https://github.com/GoogleCloudPlatform/open-match/releases/download/0.5.0-rc.2/install-example.yaml --namespace open-match
+```
+
+This command also deploys a component that continuously generates players with different properties and adds them to Open Match state storage. This is because a populated player pool is required to generate matches.
+
+### Generate Matches!
+
+In a real setup, a game backend (Director / DGS etc.) will request matches from Open Match. For demo purposes, this is simulated by a backend client that requests Open Match to continuously list matches until it runs out of players.
+
+```bash
+kubectl run om-backendclient --rm --restart=Never --image-pull-policy=Always -i --tty --image=gcr.io/open-match-public-images/openmatch-backendclient:0.5.0-rc.2 --namespace=open-match
+```
+
+If successful, the backend client should successfully generate matches, displaying players populated in Rosters.
+
+### Cleanup
+
+To delete Open Match from this cluster, simply run:
+
+```bash
+kubectl delete namespace open-match
+```

+## Disclaimer
+This software is currently alpha, and subject to change. Although Open Match has already been used to run [production workloads within Google](https://cloud.google.com/blog/topics/inside-google-cloud/no-tricks-just-treats-globally-scaling-the-halloween-multiplayer-doodle-with-open-match-on-google-cloud), but it's still early days on the way to our final goal. There's plenty left to write and we welcome contributions. **We strongly encourage you to engage with the community through the [Slack or Mailing lists](#support) if you're considering using Open Match in production before the 1.0 release, as the documentation is likely to lag behind the latest version a bit while we focus on getting out of alpha/beta as soon as possible.**

-# Open Match API
+# Open Match APIs
 
-Open Match API is exposed via [gRPC](https://grpc.io/) and HTTP REST with [Swagger](https://swagger.io/tools/swagger-codegen/).
+This directory contains the API specification files for Open Match. API documenation will be produced in a future version, although the protobuf files offer a concise description of the API calls available, along with arguments and return messages.
 
-gRPC has first-class support for [many languages](https://grpc.io/docs/) and provides the most performance. It is a RPC protocol built on top of HTTP/2 and provides TLS for secure transport.
+* [Protobuf .proto files for all APIs](./protobuf-spec/)
 
-For HTTP/HTTPS Open Match uses a gRPC proxy to serve the API. Since HTTP does not provide a structure for request/responses we use Swagger to provide a schema. You can view the Swagger docs for each service in this directory's `*.swagger.json` files. In addition each server will host it's swagger doc via `GET /swagger.json` if you want to dynamically load them at runtime.
+References:
 
-Lastly, Open Match supports insecure and TLS mode for serving the API. It's strongly preferred to use TLS mode in production but insecure mode can be used for test and local development. To help with certificates management see `tools/certgen` to create self-signed certificates.
+* [gRPC](https://grpc.io/)
+* [Language Guide (proto3)](https://developers.google.com/protocol-buffers/docs/proto3)
 
-# Open Match API Development Guide
-
-Open Match proto comments follow the same format as [this file](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/example/example.proto)
-
-If you plan to change the proto definitions, please update the comments and run `make api/api.md` to reflect the latest changes in open-match-docs.
+If you want to regenerate the golang gRPC modules (for local Open Match core component development, for example), the `protoc_go.sh` file in this directory may be of use to you!

Therefore, binary compatibility needs to be preserved\n  on changes to types. (Use versioned type names to manage\n  breaking changes.)\n\nNote: this functionality is not currently available in the official\nprotobuf release, and it is not used for type URLs beginning with\ntype.googleapis.com.\n\nSchemes other than `http`, `https` (or the empty scheme) might be\nused with implementation specific semantics."

Example:\n\n    package google.profile;\n    message Person {\n      string first_name = 1;\n      string last_name = 2;\n    }\n\n    {\n      \"@type\": \"type.googleapis.com/google.profile.Person\",\n      \"firstName\": \u003cstring\u003e,\n      \"lastName\": \u003cstring\u003e\n    }\n\nIf the embedded message type is well-known and has a custom JSON\nrepresentation, that representation will be embedded adding a field\n`value` which holds the custom JSON in addition to the `@type`\nfield. Example (for message [google.protobuf.Duration][]):\n\n    {\n      \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n      \"value\": \"1.212s\"\n    }"

However, for URLs which use the\nscheme `http`, `https`, or no scheme, one can optionally set up a type\nserver that maps type URLs to message definitions as follows:\n\n* If no scheme is provided, `https` is assumed.\n* An HTTP GET on the URL must yield a [google.protobuf.Type][]\n  value in binary format, or produce an error.\n* Applications are allowed to cache lookup results based on the\n  URL, or have them precompiled into a binary to avoid any\n  lookup. Therefore, binary compatibility needs to be preserved\n  on changes to types. (Use versioned type names to manage\n  breaking changes.)\n\nNote: this functionality is not currently available in the official\nprotobuf release, and it is not used for type URLs beginning with\ntype.googleapis.com.\n\nSchemes other than `http`, `https` (or the empty scheme) might be\nused with implementation specific semantics."

Example:\n\n    package google.profile;\n    message Person {\n      string first_name = 1;\n      string last_name = 2;\n    }\n\n    {\n      \"@type\": \"type.googleapis.com/google.profile.Person\",\n      \"firstName\": \u003cstring\u003e,\n      \"lastName\": \u003cstring\u003e\n    }\n\nIf the embedded message type is well-known and has a custom JSON\nrepresentation, that representation will be embedded adding a field\n`value` which holds the custom JSON in addition to the `@type`\nfield. Example (for message [google.protobuf.Duration][]):\n\n    {\n      \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n      \"value\": \"1.212s\"\n    }"

The name should be in a canonical form\n(e.g., leading \".\" is not accepted).\n\nIn practice, teams usually precompile into the binary all types that they\nexpect it to use in the context of Any. However, for URLs which use the\nscheme `http`, `https`, or no scheme, one can optionally set up a type\nserver that maps type URLs to message definitions as follows:\n\n* If no scheme is provided, `https` is assumed.\n* An HTTP GET on the URL must yield a [google.protobuf.Type][]\n  value in binary format, or produce an error.\n* Applications are allowed to cache lookup results based on the\n  URL, or have them precompiled into a binary to avoid any\n  lookup. Therefore, binary compatibility needs to be preserved\n  on changes to types. (Use versioned type names to manage\n  breaking changes.)\n\nNote: this functionality is not currently available in the official\nprotobuf release, and it is not used for type URLs beginning with\ntype.googleapis.com.\n\nSchemes other than `http`, `https` (or the empty scheme) might be\nused with implementation specific semantics."

Example:\n\n    package google.profile;\n    message Person {\n      string first_name = 1;\n      string last_name = 2;\n    }\n\n    {\n      \"@type\": \"type.googleapis.com/google.profile.Person\",\n      \"firstName\": \u003cstring\u003e,\n      \"lastName\": \u003cstring\u003e\n    }\n\nIf the embedded message type is well-known and has a custom JSON\nrepresentation, that representation will be embedded adding a field\n`value` which holds the custom JSON in addition to the `@type`\nfield. Example (for message [google.protobuf.Duration][]):\n\n    {\n      \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n      \"value\": \"1.212s\"\n    }"

Example (for message [google.protobuf.Duration][]):\n\n    {\n      \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n      \"value\": \"1.212s\"\n    }"

+## REST compatibility
+Follow the guidelines at https://cloud.google.com/endpoints/docs/grpc/transcoding to keep the gRPC service definitions friendly to REST transcoding. An excerpt:
+
+"Transcoding involves mapping HTTP/JSON requests and their parameters to gRPC methods and their parameters and return types (we'll look at exactly how you do this in the following sections). Because of this, while it's possible to map an HTTP/JSON request to any arbitrary API method, it's simplest and most intuitive to do so if the gRPC API itself is structured in a resource-oriented way, just like a traditional HTTP REST API. In other words, the API service should be designed so that it uses a small number of standard methods (corresponding to HTTP verbs like GET, PUT, and so on) that operate on the service's resources (and collections of resources, which are themselves a type of resource). These standard methods are List, Get, Create, Update, and Delete."
+
+It is for these reasons we don't have gRPC calls that support bi-directional streaming in Open Match.
+
+## REST API Usage
+Open Match gateway proxy transcodes any REST calls to its underlying gRPC service. Follow the [examples](https://cloud.google.com/endpoints/docs/grpc-service-config/reference/rpc/google.api#httprule) for further details.
+
+A typical REST call to Open Match backend's `CreateAssignments` service via HTTP POST request 
+```
+/v1/backend/assignments/123? \
+    assignment.rosters.name=foo&assignment.rosters.players.id=1&assignment.rosters.players.id=2
+```
+is equivalent to 
+
+```go
+CreateAssignmentsRequest(
+    Assignments(
+        name: '123',
+        rosters: [
+            Roster(name: 'foo', [Player(id: 1), Player(id: 2)])
+        ]
+    )
+)

The name should be in a canonical form\n(e.g., leading \".\" is not accepted).\n\nIn practice, teams usually precompile into the binary all types that they\nexpect it to use in the context of Any. However, for URLs which use the\nscheme `http`, `https`, or no scheme, one can optionally set up a type\nserver that maps type URLs to message definitions as follows:\n\n* If no scheme is provided, `https` is assumed.\n* An HTTP GET on the URL must yield a [google.protobuf.Type][]\n  value in binary format, or produce an error.\n* Applications are allowed to cache lookup results based on the\n  URL, or have them precompiled into a binary to avoid any\n  lookup. Therefore, binary compatibility needs to be preserved\n  on changes to types. (Use versioned type names to manage\n  breaking changes.)\n\nNote: this functionality is not currently available in the official\nprotobuf release, and it is not used for type URLs beginning with\ntype.googleapis.com.\n\nSchemes other than `http`, `https` (or the empty scheme) might be\nused with implementation specific semantics."

Example:\n\n    package google.profile;\n    message Person {\n      string first_name = 1;\n      string last_name = 2;\n    }\n\n    {\n      \"@type\": \"type.googleapis.com/google.profile.Person\",\n      \"firstName\": \u003cstring\u003e,\n      \"lastName\": \u003cstring\u003e\n    }\n\nIf the embedded message type is well-known and has a custom JSON\nrepresentation, that representation will be embedded adding a field\n`value` which holds the custom JSON in addition to the `@type`\nfield. Example (for message [google.protobuf.Duration][]):\n\n    {\n      \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n      \"value\": \"1.212s\"\n    }"

+# Core Concepts
+
+[Watch the introduction of Open Match at Unite Berlin 2018 on YouTube](https://youtu.be/qasAmy_ko2o)
+
+Open Match is designed to support massively concurrent matchmaking, and to be scalable to player populations of hundreds of millions or more. It attempts to apply stateless web tech microservices patterns to game matchmaking. If you're not sure what that means, that's okay — it is fully open source and designed to be customizable to fit into your online game architecture — so have a look a the code and modify it as you see fit.
+
+## Glossary
+
+### General
+
+* **DGS** — Dedicated game server
+* **Client** — The game client program the player uses when playing the game
+* **Session** — In Open Match, players are matched together, then assigned to a server which hosts the game _session_.  Depending on context, this may be referred to as a _match_, _map_, or just _game_ elsewhere in the industry.
+
+### Open Match
+
+* **Component** — One of the discrete processes in an Open Match deployment. Open Match is composed of multiple scalable microservices called _components_.
+* **State Storage** — The storage software used by Open Match to hold all the matchmaking state. Open Match ships with [Redis](https://redis.io/) as the default state storage.
+* **MMF** — Matchmaking function. This is the customizable matchmaking logic.
+* **Function Harness** — A GRPC serving harness that triggers the Match function.
+* **Evaluator** — Customizable evaluation logic that analyzes match proposals and approves / rejects matches.
+* **MMLogic API** — An API that provides MMF SDK functionality.
+* **Director** — The software you (as a developer) write against the Open Match Backend API. The _Director_ decides which MMFs to run, and is responsible for sending MMF results to a DGS to host the session.
+
+### Data Model
+
+* **Player** — An ID and list of attributes with values for a player who wants to participate in matchmaking.
+* **Roster** — A list of player objects.  Used to hold all the players on a single team.
+* **Filter** — A _filter_ is used to narrow down the players to only those who have an attribute value within a certain integer range.  All attributes are integer values in Open Match because [that is how indices are implemented](internal/statestorage/redis/playerindices/playerindices.go). A _filter_ is defined in a _player pool_.
+* **Player Pool** — A list of all the players who fit all the _filters_ defined in the pool.
+* **Match Object** — A protobuffer message format that contains the _profile_ and the results of the matchmaking function. Sent to the backend API from your game backend with the _roster_(s) empty and then returned from your MMF with the matchmaking results filled in.
+* **Profile** — The json blob containing all the parameters used by your MMF to select which players go into a roster together.
+* **Assignment** — Refers to assigning a player or group of players to a dedicated game server instance. Open Match offers a path to send dedicated game server connection details from your backend to your game clients after a match has been made.
+* **Ignore List** — Removing players from matchmaking consideration is accomplished using _ignore lists_.  They contain lists of player IDs that your MMF should not include when making matches.
+
+## Requirements
+
+* [Kubernetes](https://kubernetes.io/) cluster — tested with version 1.11.7.
+* [Redis 4+](https://redis.io/) — tested with 4.0.11.
+* Open Match is compiled against the latest release of [Golang](https://golang.org/) — tested with 1.11.5.
+
+## Components
+
+Open Match is a set of processes designed to run on Kubernetes. It contains these **core** components:
+
+* Frontend API
+* Backend API
+* Matchmaking Logic (MMLogic) API
+
+It also depends on these two **customizable** components.
+
+* Match Function (MMF)
+* Evaluator
+
+While **core** components are fully open source and _can_ be modified, they are designed to support the majority of matchmaking scenarios *without need to change the source code*. The Open Match repository ships with simple **customizable** MMF and Evaluator examples, but it is expected that most users will want full control over the logic in these, so they have been designed to be as easy to modify or replace as possible.
+
+### Frontend API
+
+The Frontend API accepts the player data and puts it in state storage so your Matchmaking Function (MMF) can access it.
+
+The Frontend API is a server application that implements the [gRPC](https://grpc.io/) service defined in `api/protobuf-spec/frontend.proto`. At the most basic level, it expects clients to connect and send:
+* A **unique ID** for the group of players (the group can contain any number of players, including only one).
+* A **json blob** containing all player-related data you want to use in your matchmaking function.
+
+The client is expected to maintain a connection, waiting for an update from the API that contains the details required to connect to a dedicated game server instance (an 'assignment'). There are also basic functions for removing an ID from the matchmaking pool or an existing match.
+
+### Backend API
+
+The Backend API writes match objects to state storage which the Matchmaking Functions (MMFs) access to decide which players should be matched. It returns the results from those MMFs.
+
+The Backend API is a server application that implements the [gRPC](https://grpc.io/) service defined in `api/protobuf-spec/backend.proto`. At the most basic level, it expects to be connected to your online infrastructure (probably to your server scaling manager or **director**, or even directly to a dedicated game server), and to receive:
+* A **unique ID** for a matchmaking profile.
+* A **json blob** containing all the matching-related data and filters you want to use in your matchmaking function.
+* An optional list of **roster**s to hold the resulting teams chosen by your matchmaking function.
+* An optional set of **filters** that define player pools your matchmaking function will choose players from.
+
+Your game backend is expected to maintain a connection, waiting for 'filled' match objects containing a roster of players. The Backend API also provides a return path for your game backend to return dedicated game server connection details (an 'assignment') to the game client, and to delete these 'assignments'.
+
+### Matchmaking Logic (MMLogic) API
+
+The MMLogic API provides a series of gRPC functions that act as a Matchmaking Function SDK.  Much of the basic, boilerplate code for an MMF is the same regardless of what players you want to match together.  The MMLogic API offers a gRPC interface for many common MMF tasks, such as:
+
+1. Reading a profile from state storage.
+1. Running filters on players in state strorage. It automatically removes players on ignore lists as well!
+1. Removing chosen players from consideration by other MMFs (by adding them to an ignore list). It does it automatically for you when writing your results!
+1. Writing the matchmaking results to state storage.
+1. (Optional, NYI) Exporting MMF stats for metrics collection.
+
+More details about the available gRPC calls can be found in the [API Specification](api/protobuf-spec/messages.proto).
+
+**Note**: using the MMLogic API is **optional**.  It tries to simplify the development of MMFs, but if you want to take care of these tasks on your own, you can make few or no calls to the MMLogic API as long as your MMF still completes all the required tasks.  Read the [Matchmaking Functions section](#matchmaking-functions-mmfs) for more details of what work an MMF must do.
+
+### Evaluator
+
+The Evaluator resolves conflicts when multiple MMFs select the same player(s). Evaluator is provided by the developer (sample included in Open Match).
+
+The Evaluator runs forever, looping over a configured interval, checking if MMFs have completed execution or if certain time interval has passed. Upon reaching those conditions, the Evaluator calls the Evaluation Function (to be modified by the user) with the proposals to choose from. The sample Evaluation function looks at all the proposals, and if multiple proposals contain the same player(s), it breaks the tie. In many simple matchmaking setups with only a few game modes and well-tuned matchmaking functions, the Evaluator may functionally be a no-op or first-in-first-out algorithm. In complex matchmaking setups where, for example, a player can queue for multiple types of matches, the Evaluator provides the critical customizability to evaluate all available proposals and approve those that will passed to your game servers.
+
+Large-scale concurrent matchmaking functions is a complex topic, and users who wish to do this are encouraged to engage with the [Open Match community](https://github.com/GoogleCloudPlatform/open-match#get-involved) about patterns and best practices.
+
+### Matchmaking Functions (MMFs)
+
+Matchmaking Functions (MMFs) are implemented by the developer and are hosted as a gRPC service. Open Match provides a harness (currently for golang) that handles the broiler-plate Open Match communitation, gRPC server setup etc., so that the user only has to write a function that accepts a set of player pools and a match profile and returns a proposal based on some core match making logic. An MMF is called each time a request to generate a match is received. At a high level, an MMF needs to generate a proposal using the given players, match profile and its custom match making logic and return the proposal to the calling harness.
+**Note**: Currently Open Match only has a golang harness. To add an MMF in any other language, a harness needs to be implemented in that language.
+
+## Example Tooling
+
+To see Open Match, in action, here are some basic tools that are provided as samples:
+
+* `test/cmd/clientloadgen/` is a (VERY) basic client load simulation tool.  It endlessly writes players into state storage so you can test your backend integration, and run your custom MMFs and Evaluators (which are only triggered when there are players in the pool).
+
+* `examples/backendclient` is a fake client for the Backend API.  It pretends to be a dedicated game server backend connecting to Open Match and sending in a match profile to fill and receives completed matches. It can call Create / List matches.
+
+* `test/cmd/frontendclient/` is a fake client for the Frontend API.  It pretends to be group of real game clients connecting to Open Match.  It requests a game, then dumps out the results each player receives to the screen.

-On Debian-based Linux you can install all the required packages (except Go) by
-running:
+Here are the instructions to set up a local repository for Open Match.
 
 ```bash
-sudo apt-get update
-sudo apt-get install -y -q make google-cloud-sdk git unzip tar
-```
-
-*It's recommended that you install Go using their instructions because package
-managers tend to lag behind the latest Go releases.*
-
-## Get the Code
-
-```bash
-# Create a directory for the project.
-mkdir -p $HOME/workspace
-cd $HOME/workspace
-# Download the source code.
-git clone https://github.com/googleforgames/open-match.git
+# Install Open Match Toolchain Dependencies (for Debian, other OSes including Mac OS X have similar dependencies)
+sudo apt-get update; sudo apt-get install -y -q python3 python3-virtualenv virtualenv make google-cloud-sdk git unzip tar
+mkdir -p $HOME/<workspace>
+cd $HOME/<workspace>
+git clone https://github.com/GoogleCloudPlatform/open-match.git
 cd open-match
-# Print the help for the Makefile commands.
-make

-*Typically for contributing you'll want to
-[create a fork](https://help.github.com/en/articles/fork-a-repo) and use that
-but for purpose of this guide we'll be using the upstream/master.*
+## Compiling From Source
 
-## Building code and images
+The easiest way to build Open Match is to use the [Makefile](Makefile). This section assumes that you have followed the steps to [Setup Local Open Match Repository](#local-repository-setup).
+
+You will also need [Docker](https://docs.docker.com/install/) and [Go 1.12+](https://golang.org/dl/) installed.
+
+To build all the artifacts of Open Match, please run the following commands:
 
 ```bash
-# Reset workspace
-make clean
-# Run tests
-make test
-# Build all the images.
-make build-images -j$(nproc)
-# Push images to gcr.io (requires Google Cloud SDK installed)
-make push-images -j$(nproc)
-# Push images to Docker Hub
-make REGISTRY=mydockerusername push-images -j$(nproc)
-# Generate Kubernetes installation YAML files (Note that the trailing '/' is needed here)
-make install/yaml/
+# Downloads all the tools needed to build Open Match
+make install-toolchain
+# Generates protocol buffer code files
+make all-protos
+# Builds all the binaries
+make all
+# Builds all the images.
+make build-images
 ```
 
-_**-j$(nproc)** is a flag to tell make to parallelize the commands based on
-the number of CPUs on your machine._
+After successfully building, run `docker images` to see all the images that were build.
 
-## Deploying to Kubernetes
+Before creating a pull request you can run `make local-cloud-build` to simulate a Cloud Build run to check for regressions.
 
-Kubernetes comes in many flavors and Open Match can be used in any of them.
+The [Build Queue](https://console.cloud.google.com/cloud-build/builds?project=open-match-build) runs against all PRs, requires membership to [open-match-discuss@googlegroups.com](https://groups.google.com/forum/#!forum/open-match-discuss).
 
-_We support GKE ([setup guide](gcloud.md)), Minikube, and Kubernetes in Docker (KinD) in the Makefile.
-As long as kubectl is configured to talk to your Kubernetes cluster as the
-default context the Makefile will honor that._
+## Deploy Open Match to Google Cloud Platform
+
+Create a GCP project via [Google Cloud Console](https://console.cloud.google.com/). Billing must be enabled but if you're a new customer you can get some [free credits](https://cloud.google.com/free/). When you create a project you'll need to set a Project ID, if you forget it you can see it here, https://console.cloud.google.com/iam-admin/settings/project.
+
+Now install [Google Cloud SDK](https://cloud.google.com/sdk/) which is the command line tool to work against your project. The following commands log you into your GCP Project.
 
 ```bash
-# Step 1: Create a Kubernetes (k8s) cluster
-# KinD cluster: make create-kind-cluster/delete-kind-cluster
-# GKE cluster: make create-gke-cluster/delete-gke-cluster
-# or create a local Minikube cluster
-make create-gke-cluster
-# Step 2: Build and Push Open Match Images to gcr.io
-make push-images -j$(nproc)
-# Step 3: Install Open Match in the cluster.
+# Login to your Google Account for GCP.
+gcloud auth login
+gcloud config set project $YOUR_GCP_PROJECT_ID
+# Enable GCP services
+gcloud services enable containerregistry.googleapis.com
+gcloud services enable container.googleapis.com
+# Test that everything is good, this command should work.
+gcloud compute zones list
+```
+
+This section assumes that you have followed the steps to [Setup Local Open Match Repository](#local-repository-setup). Once everything is setup you can deploy Open Match by creating a cluster in Google Kubernetes Engine (GKE).
+
+```bash
+# Create a GKE Cluster and install Helm
+make create-gke-cluster push-helm
+# Push images to Registry
+make push-images
+# Deploy Open Match
 make install-chart
-
-# Create a proxy to Open Match pods so that you can access them locally.
-# This command consumes a terminal window that you can kill via Ctrl+C.
-# You can run `curl -X POST http://localhost:51504/v1/frontend/tickets` to send
-# a DeleteTicket request to the frontend service in the cluster.
-# Then try visiting http://localhost:3000/ and view the graphs.
-make proxy
-
-# Teardown the install
-make delete-chart
 ```
 
-## Iterating
-While iterating on the project, you may need to:
-1. Install/Run everything
-2. Make some code changes
-3. Make sure the changes compile by running `make test`
-4. Build and push Docker images to your personal registry by running `make push-images -j$(nproc)`
-5. Deploy the code change by running `make install-chart`
-6. Verify it's working by [looking at the logs](#accessing-logs) or looking at the monitoring dashboard by running `make proxy-grafana`
-7. Tear down Open Match by running `make delete-chart`
+This will install all Open Match core components to the kubernetes cluster. Once deployed you can view the jobs in [Cloud Console](https://console.cloud.google.com/kubernetes/workload).
 
-## Accessing logs
-To look at Open Match core services' logs, run:
-```bash
-# Replace open-match-frontend with the service name that you would like to access
-kubectl logs -n open-match svc/open-match-frontend
+Run `kubectl --namespace open-match get pods,svc` to verify if the deployment succeded. If everything started correctly, the output should look like:
+
+```
+$ kubectl --namespace open-match get pods,svc

-## API References
-While integrating with Open Match you may want to understand its API surface concepts or interact with it and get a feel for how it works.
+## End-to-End testing
 
-The APIs are defined in `proto` format under the `api/` folder, with references available at [open-match.dev](https://open-match.dev/site/docs/reference/api/).
+### Example MMF, Evaluator
 
-You can also run `make proxy-ui` to exposes the Swagger UI for Open Match locally on your computer after [deploying it to Kubernetes](#deploying-to-kubernetes), then go to http://localhost:51500 and view the REST APIs as well as interactively call Open Match.
+When Open Match is setup, it requires a Match Function and an Evaluator to be set up that it will call into at runtime when requests to generate matches are received. Open Match itself provides harness code (currently only for golang) that abstracts the complexity of setting up the Match Function and Evaluator as GRPC services. You do not need to modify the harness code but simply the actual Match Function, Evaluator Function to suit your game's needs. Open Match includes sample Match function and Evaluation Function as described below:
 
-By default you will be talking to the frontend server but you can change the target API url to any of the following:
+* `examples/functions/golang/grpc-serving` is a sample Match function that is built using the GRPC harness. The function scans a simple profile, populating a player into each Roster slot that matches the requested player pool. This function is over-simplified simply matching player pools to roster slots. You will need to modify this function to add your match making logic.
 
- * api/frontend.swagger.json
- * api/backend.swagger.json
- * api/synchronizer.swagger.json
- * api/query.swagger.json
+* `examples/evaluators/golang/serving` is a sample evaluator function that is called by an evaluator harness that runs as forever-runnig kubernetes job. The function is triggered each time there are results to evaluate. The current sample simply approves matches with unique players, identifies the ones with overlap and approves the first overlapping player match rejecting the rest. You would need to build your own evaluation logic with this sample as a reference.
 
-For a more current list refer to the api/ directory of this repository. Also matchfunction.swagger.json is not supported.
+### Example Tooling
 
-## IDE Support
+Once Open Match core components are set up and your Match Function and Evaluator GRPC services are running, Open Match functionality is triggered when new players request assignments and when the game backend requests matches. To see Open Match, in action, here are some basic tools that are provided as samples. Note that these tools are meant to exercise Open Match functionality and should only be used as a reference point when building similar abilities into your components using Open Match.
 
-Open Match is a standard Go project so any IDE that understands that should
-work. We use [Go Modules](https://github.com/golang/go/wiki/Modules) which is a
-relatively new feature in Go so make sure the IDE you are using was built around
-Summer 2019. The latest version of
-[Visual Studio Code](https://code.visualstudio.com/download) supports it.
+* `test/cmd/clientloadgen/` is a (VERY) basic client load simulation tool.  It does **not** test the Frontend API - in fact, it ignores it and writes players directly to state storage on its own.  It doesn't do anything but loop endlessly, writing players into state storage so you can test your backend integration, and run your custom MMFs and Evaluators (which are only triggered when there are players in the pool).
 
-If your IDE is too old you can create a
-[Go workspace](https://golang.org/doc/code.html#Workspaces).
+* `examples/backendclient` is a fake client for the Backend API.  It pretends to be a dedicated game server backend connecting to Open Match and sending in a match profile to fill.  Once it receives a match object with a roster, it will also issue a call to assign the player IDs, and gives an example connection string.  If it never seems to get a match, make sure you're adding players to the pool using the other two tools. **Note**: If you run this by itself, expect it to wait about 30 seconds, then return a result of 'insufficient players' and exit - this is working as intended.  Use the client load simulation tool below to add players to the pool or you'll never be able to make a successful match.
+
+* `test/cmd/frontendclient/` is a fake client for the Frontend API.  It pretends to be group of real game clients connecting to Open Match.  It requests a game, then dumps out the results each player receives to the screen until you press the enter key. **Note**: If you're using the rest of these test programs, you're probably using the Backend Client below.  The default profiles that command sends to the backend look for many more than one player, so if you want to see meaningful results from running this Frontend Client, you're going to need to generate a bunch of fake players using the client load simulation tool at the same time. Otherwise, expect to wait until it times out as your matchmaker never has enough players to make a successful match. Also, if the simulator has generated significant load, the player injected by te Frontend Client may still not find a match by the timeout duration and exit.
+
+### Setting up an E2E scenario
+
+These steps assume that you already have [deployed core Open Match to a cluster](deploy-open-match-to-google-cloud-platform). Once Open Match is deployed, run the below command to deploy the Match Function Harness, the Evaluator and the Client Load Generator to the Open Match cluster.
 
 ```bash
-# Create the Go workspace in $HOME/workspace/ directory.
-mkdir -p $HOME/workspace/src/open-match.dev/
-cd $HOME/workspace/src/open-match.dev/
-# Download the source code.
-git clone https://github.com/googleforgames/open-match.git
-cd open-match
-export GOPATH=$HOME/workspace/
+# Deploy Open Match
+make install-example-chart
 ```
 
-## Pull Requests
+Once this succeeds, run the below command to validate that these components are up and running as expected (in addition to the Open Match core components):
 
-If you want to submit a Pull Request, `make presubmit` can catch most of the issues your change can run into.
+```bash
+$kubectl --namespace open-match get pods,svc
 
-Our [continuous integration](https://console.cloud.google.com/cloud-build/builds?project=open-match-build)
-runs against all PRs. In order to see your build results you'll need to
-become a member of
-[open-match-discuss@googlegroups.com](https://groups.google.com/forum/#!forum/open-match-discuss).

+```
+
+At this point, the Evaluator and Match Function are both running and a client load generator is continuously adding players to the state storage. To see match generation in action, run the following command:
+
+```bash
+make run-backendclient
+```
+
+Some other handy commands:
+
+```bash
+# Cleanup the installation
+make delete-chart delete-example-chart
+
+# To install a pre-built image without building again:
+make REGISTRY=$REGISTRY TAG=$TAG install-chart install-example-chart
+make REGISTRY=$REGISTRY TAG=$TAG install-example-chart
+make REGISTRY=$REGISTRY TAG=$TAG run-backendclient
+```
+
+**Note**: The programs provided below are just bare-bones manual testing programs with no automation and no claim of code coverage. This sparseness of this part of the documentation is because we expect to discard all of these tools and write a fully automated end-to-end test suite and a collection of load testing tools, with extensive stats output and tracing capabilities before 1.0 release. Tracing has to be integrated first, which will be in an upcoming release.
+
+In the end: *caveat emptor*. These tools all work and are quite small, and as such are fairly easy for developers to understand by looking at the code and logging output. They are provided as-is just as a reference point of how to begin experimenting with Open Match integrations.

+Complete Milestone
+------------------
+- [ ] Create the next version milestone, use [semantic versioning](https://semver.org/) when naming it to be consistent with the [Go community](https://blog.golang.org/versioning-proposal).
+- [ ] Visit the [milestone](https://github.com/GoogleCloudPlatform/open-match/milestone).
+  - [ ] Open a document for a draft [release notes](release.md).
+  - [ ] Add the milestone tag to all PRs and issues that were merged since the last milestone. Look at the [releases page](https://github.com/GoogleCloudPlatform/open-match/releases) and look for the "X commits to master since this release" for the diff. The link resolves to, https://github.com/GoogleCloudPlatform/open-match/compare/v{version}...master.

+  - [ ] Review all [issues in milestone](https://github.com/GoogleCloudPlatform/open-match/milestones) for proper [labels](https://github.com/GoogleCloudPlatform/open-match/labels) (ex: area/build).
+  - [ ] Review all [milestone-less closed PRs](https://github.com/GoogleCloudPlatform/open-match/pulls?q=is%3Apr+is%3Aclosed+no%3Amilestone) and assign the appropriate milestone.
+  - [ ] Review all [PRs in milestone](https://github.com/GoogleCloudPlatform/open-match/milestones) for proper [labels](https://github.com/GoogleCloudPlatform/open-match/labels) (ex: area/build).
+  - [ ] View all open entries in milestone and move them to a future milestone if they aren't getting closed in time. https://github.com/GoogleCloudPlatform/open-match/milestones/v{version}
+  - [ ] Review all closed PRs against the milestone. Put the user visible changes into the release notes using the suggested format. https://github.com/GoogleCloudPlatform/open-match/pulls?q=is%3Apr+is%3Aclosed+milestone%3Av{version}
+  - [ ] Review all closed issues against the milestone. Put the user visible changes into the release notes using the suggested format. https://github.com/GoogleCloudPlatform/open-match/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aclosed+milestone%3Av{version}
+  - [ ] Verify the [milestone](https://github.com/GoogleCloudPlatform/open-match/milestones) is effectively 100% at this point with the exception of the release issue itself.
+
+TODO: Add details for appropriate tagging for issues.
+
+Build Artifacts
+---------------
+- [ ] Create a PR to bump the version.
+  - [ ] Open the [`Makefile`](makefile-version) and change BASE_VERSION value. Release candidates use the -rc# suffix.
+  - [ ] Open the [`install/helm/open-match/Chart.yaml`](om-chart-yaml-version) and [`install/helm/open-match-example/Chart.yaml`](om-example-chart-yaml-version) and change the `appVersion` and `version` entries.
+  - [ ] Open the [`install/helm/open-match/values.yaml`](om-values-yaml-version) and [`install/helm/open-match-example/values.yaml`](om-example-values-yaml-version) and change the `tag` entries.
+  - [ ] Open the [`site/config.toml`]  and change the `release_branch` and `release_version` entries.
+  - [ ] Open the [`README.md`](readme-deploy) update the version references.
+  - [ ] Run `make clean release`
+  - [ ] There might be additional references to the old version but be careful not to change it for places that have it for historical purposes.
+  - [ ] Submit the pull request.
+- [ ] Take note of the git hash in master, `git checkout master && git pull master && git rev-parse HEAD`
+- [ ] Go to [Cloud Build](https://pantheon.corp.google.com/cloud-build/triggers?project=open-match-build), under Post Submit click "Run Trigger".
+- [ ] Go to the History section and find the "Post Submit" build that's running. Wait for it to go Green. If it's red fix error repeat this section. Take note of version tag for next step.
+- [ ] Run `./docs/governance/templates/release.sh {source version tag} {version}` to copy the images to open-match-public-images.
+- [ ] Create a *draft* release with the [release template][release-template]
+  - [ ] Make a `tag` with the release version. The tag must be v{version}. Example: v0.5.0. Append -rc# for release candidates. Example: v0.5.0-rc1.
+  - [ ] Copy the files from `build/release/` generated from `make release` from earlier as release artifacts.
+- [ ] Run `make delete-gke-cluster create-gke-cluster push-helm sleep-10 install-chart install-example-chart` and verify that the pods are all healthy.
+- [ ] Run `make delete-gke-cluster create-gke-cluster` and run through the instructions under the [README](readme-deploy), verify the pods are healthy. You'll need to adjust the path to the `install/yaml/install.yaml` and `install/yaml/install-example.yaml` in your local clone since you haven't published them yet.
+- [ ] Publish the [Release](om-release) in Github.

+## Open Source Software integrations
+
+### Structured Logging - Logrus
+
+Logging for Open Match uses the [Golang logrus module](https://github.com/sirupsen/logrus) to provide structured logs. Logs are output to `stdout` in each component, as expected by Docker and Kubernetes. Level and format are configurable via config/matchmaker_config.json. If you have a specific log aggregator as your final destination, we recommend you have a look at the logrus documentation as there is probably a log formatter that plays nicely with your stack.
+
+### Instrumentation - OpenCensus
+
+Open Match uses [OpenCensus](https://opencensus.io/) for metrics instrumentation. The [gRPC](https://grpc.io/) integrations are built-in, and Golang redigo module integrations are incoming, but [haven't been merged into the official repo](https://github.com/opencensus-integrations/redigo/pull/1). All of the core components expose HTTP `/metrics` endpoints on the port defined in `config/matchmaker_config.json` (default: 9555) for Prometheus to scrape. If you would like to export to a different metrics aggregation platform, we suggest you have a look at the OpenCensus documentation — there may be one written for you already, and switching to it may be as simple as changing a few lines of code.
+
+**Note:** A standard for instrumentation of MMFs is planned.
+
+### State Storage - Redis
+
+By default, Open Match expects you to run Redis *somewhere*. Connection information can be put in the config file (`matchmaker_config.json`) for any Redis instance reachable from the [Kubernetes namespace](https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/). By default, Open Match sensibly runs in the Kubernetes `default` namespace. In most instances, we expect users will run a copy of Redis in a pod in Kubernetes, with a service pointing to it.
+
+* HA configurations for Redis aren't implemented by the provided Kubernetes resource definition files, but Open Match expects the Redis service to be named `redis`, which provides an easier path to multi-instance deployments.

+# Open Match Roadmap
+
+Open Match is currently at release 0.4.0. Open Match 0.5.0 currently has a Release Candidate and we are targeting to cut the release on 04/25/2019.
+
+Releases can be found on the [releases page](https://github.com/GoogleCloudPlatform/open-match/releases).
+
+Below sections detail the themes and the roadmap for the future releases. The tasks listed for the 0.6.0 release have been finalized and are well understood. As for the 0.7.0 and beyond, the tasks currently identified are listed. These are subject to change as we make our way through 0.6.0 release and get more feedback from the community.
+
+## 0.5.0 - Usability
+
+The primary focus of the 0.5 release is usability. The goal for this release is to make Open Match easy to build and deploy and have solid supporting documentation. Users should be able to try Open Match 0.5.0 functionality and experiment with its features, MMFs etc. Here are some planned features for this release:
+
+- [X] Add support to invoke MMFs as a gRPC function call.
+- [X] Provide a gRPC serving harness and an example MMF built using this harness. (golang based).
+- [X] Provide a evaluation harness and a sample evaluator using this harness (golang based)
+- [X] Deprecate the k8s based job scheduling mechanism for MMFs, Evaluator in favor of hosted MMFs, Evaluator.
+- [X] Switch all core Open Match services to use gRPC style request / response protos.
+- [X] Documentation: Add basic user, developer documentation and set up the Open Match website.
+- [X] Create and document a formal release process.
+- [X] Improve developer experience (simplify compiling, deploying and validating)
+
+## 0.6.0 - API changes, Maturity
+
+In 0.6.0 release, we are revisiting the Data Model and the API surface exposed by Open Match. The goal of this release is to front-load a major API refactoring that will facilitate achieving scale and other productionizing goals in forthcoming releases. Although breaking chagnes can happen any time till 1.0, the goal is to implement any major breaking changes in 0.6.0 so that future chagnes if any are relatively minor. Customer should be able to start building their Match Makers using the 0.6.0 API surface.
+
+Here are the tasks planned for 0.6.0 release:
+
+- [ ] Implement the new Data model and the API changes for the Frontend, Backend and MMLogic API [Change Proposal](https://github.com/GoogleCloudPlatform/open-match/issues/279)
+- [ ] Accept multiple proposals per MMF execution.
+- [ ] Remove persistance of matches and proposals from Open Match state storage.
+- [ ] Implement synchronized evaluation to eliminate use of state storage during evaluation.
+- [ ] Introduce test framework for unit testing, Component testing and E2E testing.
+- [ ] Add unit tests, component tests and integration tests for Open Match core components and examples.
+- [ ] Update harness, evaluator, mmf samples etc., to reflect the API changes.
+- [ ] Update documentation, website to reflect 0.6.0 API changes.
+
+## 0.7.0 - Scale, Operationalizing
+
+Features for 0.7.0 are targeted to enable Open Match to be productionizable. Note that as we identify more feature work past 0.6.0, these tasks may get pushed to future releases. However, these are core tasks that need to be addressed before Open Match reaches 1.0.
+
+- [ ] Introduce Test framework for load, performance testing
+- [ ] Automated Load / performance / scale tests
+- [ ] Test results Dashboard
+- [ ] Add support for Instrumentation, Monitoring, Dashboards
+- [ ] Add support or Metrics collection, Analytics, Dashboards
+- [ ] Identify Autoscaling patterns for each component and configure them.
+
+## Other Features
+
+Below are additional features that are not tied to a specific release but will be added incrementally across releases:
+
+- [ ] Harness support for Python, PHP, C#, C++
+- [ ] User Guide for Open Match, Tutorials
+- [ ] Developer Guide for Open Match
+- [ ] APIs & Reference
+- [ ] Concept Documentation
+- [ ] Website Improvements
+
+## 1.1.0
+
+Below are the features that have been identified but are not considered critical for Open Match (as a match making framework) to itself reach 1.0. Any other features that are related to Open Match ecosystem but not a part of the framework itself can be listed here. These features may not necessarily wait for Open Match 1.0 and can be implemented before that - but any of the currently identified 1.0 tasks are higher in priority than these to make Open Match production ready.
+
+- [ ] Canonical usable examples out of box.
+- [ ] KNative support to run MMFs
+- [ ] OSS Director to integrate with Agones, other DGS backends
+
