+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 commands below are pasted from the 0.5 release.  make the necessary
-changes to match your naming & environment.*
+**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 your fork of the Open Match repository.**
+### 1. Clone Repository
 
 ```shell
+# Clone your fork of the Open Match repository.
 git clone git@github.com:afeddersen/open-match.git
-```
-**2. Move into the new open-match directory.**
-
-```shell
+# Change directory to the git repository.
 cd open-match
-```
-
-**3. Configure a remote that points to the upstream repository. This is required to sync changes you make in a fork with the original repository.  Note: Upstream is the gatekeeper of the project or the source of truth to which you wish to contribute.**
-
-```shell
+# Add a remote, you'll be pushing to this.
 git remote add upstream https://github.com/googleforgames/open-match.git
 ```
 
-**3. Fetch the branches and their respective commits from the upstream repo.**
+### 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
-git fetch upstream
+# Create a local release branch.
+git checkout -b release-0.5 upstream/master
+# Push the branch upstream.
+git push upstream release-0.5
 ```
 
-**4.  Create a local release branch that tracks upstream and check it out.**
+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.**

+- [ ] 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.

-### 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/googleforgames/open-match/issues/41)|[PR #48](https://github.com/googleforgames/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/googleforgames/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/googleforgames/open-match/issues/41) if it fills our needs, feel free to contribute!

-      "description": "- Simple to use and understand for most users\n- Flexible enough to meet unexpected needs\n\n# Overview\n\nThe `Status` message contains three pieces of data: error code, error\nmessage, and error details. The error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

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

-      "description": "- Simple to use and understand for most users\n- Flexible enough to meet unexpected needs\n\n# Overview\n\nThe `Status` message contains three pieces of data: error code, error\nmessage, and error details. The error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

-      "description": "- Simple to use and understand for most users\n- Flexible enough to meet unexpected needs\n\n# Overview\n\nThe `Status` message contains three pieces of data: error code, error\nmessage, and error details. The error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

-      "description": "- Simple to use and understand for most users\n- Flexible enough to meet unexpected needs\n\n# Overview\n\nThe `Status` message contains three pieces of data: error code, error\nmessage, and error details. The error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

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 error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

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

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

The error code should be an enum value of\n[google.rpc.Code][google.rpc.Code], but it may accept additional error codes\nif needed.  The error message should be a developer-facing English message\nthat helps developers *understand* and *resolve* the error. If a localized\nuser-facing error message is needed, put the localized message in the error\ndetails or localize it in the client. The optional error details may contain\narbitrary information about the error. There is a predefined set of error\ndetail types in the package `google.rpc` that can be used for common error\nconditions.\n\n# Language mapping\n\nThe `Status` message is the logical representation of the error model, but it\nis not necessarily the actual wire format. When the `Status` message is\nexposed in different client libraries and different wire protocols, it can be\nmapped differently. For example, it will likely be mapped to some exceptions\nin Java, but more likely mapped to some error codes in C.\n\n# Other uses\n\nThe error model and the `Status` message can be used in a variety of\nenvironments, either with or without APIs, to provide a\nconsistent developer experience across different environments.\n\nExample uses of this error model include:\n\n- Partial errors. If a service needs to return partial errors to the client,\n    it may embed the `Status` in the normal response to indicate the partial\n    errors.\n\n- Workflow errors. A typical workflow has multiple steps. Each step may\n    have a `Status` message for error reporting.\n\n- Batch operations. If a client uses batch request and batch response, the\n    `Status` message should be used directly inside batch response, one for\n    each error sub-response.\n\n- Asynchronous operations. If an API call embeds asynchronous operation\n    results in its response, the status of those operations should be\n    represented directly using the `Status` message.\n\n- Logging. If some API errors are stored in logs, the message `Status` could\n    be used directly after any stripping needed for security/privacy reasons.",

-## Interaction
+## 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`
 
-Before integrating with Open Match you can manually interact with it to get a feel for how it works.
+## 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
+```
 
-`make proxy-ui` exposes the Swagger UI for Open Match locally on your computer.
-You can then go to http://localhost:51500 and view the API as well as interactively call Open Match.
+## 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.
+
+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/).
+
+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.
 
 By default you will be talking to the frontend server but you can change the target API url to any of the following:
 
  * api/frontend.swagger.json
  * api/backend.swagger.json
  * api/synchronizer.swagger.json
- * api/mmlogic.swagger.json
+ * api/query.swagger.json
 
 For a more current list refer to the api/ directory of this repository. Also matchfunction.swagger.json is not supported.

-# Create a GKE Cluster
-
-Below are the steps to create a GKE cluster in Google Cloud Platform.
-
-* Create a GCP project via [Google Cloud Console](https://console.cloud.google.com/).
-* Billing must be enabled. 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.
-* Install [Google Cloud SDK](https://cloud.google.com/sdk/) which is the command line tool to work against your project.
-
-Here are the next steps using the gcloud tool.  
-
-```bash
-# Login to your Google Account for GCP
-gcloud auth login
-gcloud config set project $YOUR_GCP_PROJECT_ID
-
-# Enable necessary 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
-
-# Create a GKE Cluster in this project
-gcloud container clusters create --machine-type n1-standard-2 open-match-dev-cluster --zone us-west1-a --tags open-match

+## How to use this framework
+
+This is the framework that we use to benchmark Open Match against different matchmaking scenarios. For now (02/24/2020), this framework supports a Battle Royale, a Basic 1v1 matchmaking, and a Team Shooter scenario. You are welcome to write up your own `Scenario`, test it, and share the number that you are able to get to us. 
+
+1. The `Scenario` struct under the `scenarios/scenarios.go` file defines the parameters that this framework currently support/plan to support.
+2. Each subpackage `battleroyal`, `firstmatch`, and `teamshooter` implements to `GameScenario` interface defined under `scenarios/scenarios.go` file. Feel free to write your own benchmark scenario by implementing the interface. 
+   - Ticket   `func() *pb.Ticket` - Tickets generator
+   - Profiles `func() []*pb.MatchProfile` - Profiles generator
+   - MMF      `MatchFunction(p *pb.MatchProfile, poolTickets map[string][]*pb.Ticket) ([]*pb.Match, error)` - Custom matchmaking logic using a MatchProfile and a map struct that contains the mapping from pool name to the tickets of that pool.
+   - Evaluate `Evaluate(stream pb.Evaluator_EvaluateServer) error` - Custom logic implementation of the evaluator.
+
+Follow the instructions below if you want to use any of the existing benchmarking scenarios.
+
+1. Open the `scenarios.go` file under the scenarios directory.
+2. Change the value of the `ActiveScenario` variable to the scenario that you would like Open Match to run against.
+3. Make sure you have `kubectl` connected to an existing Kubernetes cluster and run `make push-images` followed by `make install-scale-chart` to push the images and install Open Match core along with the scale components in the cluster.
+4. Run `make proxy` 
+   - Open `localhost:3000` to see the Grafana dashboards.
+   - Open `localhost:9090` to see the Prometheus query server.
+   - Open `localhost:[COMPONENT_HTTP_ENDPOINT]/help` to see how to access the zpages.

-Open Match Helm Chart
-=====================
+### Open Match Helm Chart Templates
+This directory contains the [helm](https://helm.sh/ "helm") chart templates used to customize and deploy Open Match.
 
-Open Match provides a Helm chart to quickly 
+Templates under the `templates/` directory are for the core components in Open Match - e.g. backend, frontend, query, synchronizor, some security policies, and configmaps are defined under this folder.
 
-```bash
-# Install Helm and Tiller
-# See https://github.com/helm/helm/releases for 
-cd /tmp && curl -Lo helm.tar.gz https://storage.googleapis.com/kubernetes-helm/helm-v2.13.0-linux-amd64.tar.gz && tar xvzf helm.tar.gz --strip-components 1 && mv helm $(PREFIX)/bin/helm && mv tiller $(PREFIX)/bin/tiller
+Open Match also provides templates for optional components that are disabled by default under the `subcharts/` directory.
+1. `open-match-customize` contains flexible templates to deploy your own matchfunction and evaluator.
+2. `open-match-telemetry` contains monitoring supports for Open Match, you may choose to enable/disable [jaeger](https://www.jaegertracing.io/ "jaeger"), [prometheus](http://prometheus.io "prometheus"), [stackdriver](https://cloud.google.com/stackdriver/ "stackdriver"), and [grafana](https://grafana.com/ "grafana") by overriding the config values in the provided templates.
 
-# Install Helm to Kubernetes Cluster
-kubectl create serviceaccount --namespace kube-system tiller
-helm init --service-account tiller --force-upgrade
-kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
-# Run if RBAC is enabled.
-kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'  
+You may control the behavior of Open Match by overriding the configs in `install/helm/open-match/values.yaml` file. Here are a few examples:
 
-# Deploy Open Match
-helm upgrade --install --wait --debug open-match \
-    install/helm/open-match \
-    --namespace=open-match \
-    --set openmatch.image.registry=$(REGISTRY) \
-    --set openmatch.image.tag=$(TAG)
+```diff
+# install/helm/open-match/values.yaml
+# 1. Configs under the `global` section affects all components - including components in the subcharts.
+# 2. Configs under the subchart name - e.g. `open-match-customize` only affects the settings in that subchart.
+# 3. Otherwise, the configs are for core components (templates in the parent chart) only.
