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

+## 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`

+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

+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.

+## 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.
