+# BuildKite configuration
+
+This folder contains configuration for the [BuildKite](https://buildkite.com) based CI checks for 
+this repository.
+
+BuildKite is a CI provider that provides build coordination and reports while we provide the 
+infrastructure.
+
+CI runs are triggered by new PRs and will show up on the GitHub checks interface, along with the 
+other current CI solutions.
+
+Currently it is only used for tests on Windows platforms.
+
+
+## The build pipeline
+
+BuildKite uses a pipeline for each repository. The `pipeline.yml` file defines pipeline 
+[build steps](https://buildkite.com/docs/pipelines/defining-steps) for this repository.
+
+Run results can be seen in the GitHub checks interface and in the 
+[pipeline dashboard](https://buildkite.com/angular/angular).
+
+Although most configuration is done via `pipeline.yml`, some options are only available
+in the online [pipeline settings](https://buildkite.com/angular/angular/settings).
+
+
+## Infrastructure
+
+BuildKite does not provide the host machines where the builds runs, providing instead the
+[BuildKite Agent](https://buildkite.com/docs/agent/v3) that should be run our own infrastructure.
+
+
+### Agents
+
+This agent polls the BuildKite API for builds, runs them, and reports back the results.
+Agents are the unit of concurrency: each agent can run one build at any given time. 
+Adding agents allows more builds to be ran at the same time.
+
+Individual agents can have tags, and pipeline steps can target only agents with certain tags via the
+`agents` field in `pipeline.yml`.
+For example: agents on Windows machines are tagged as `windows`, and the Windows specific build 
+steps list `windows: true` in their `agents` field.
+
+You can see the current agent pool, along with their tags, in the 
+[agents list](https://buildkite.com/organizations/angular/agents).
+
+
+### Our host machines
+
+We use [Google Cloud](https://cloud.google.com/) as our cloud provider, under the 
+[Angular project](https://console.cloud.google.com/home/dashboard?project=internal-200822).
+To access this project you need need to be logged in with a Google account that's a member of 
+team@angular.io. 
+For googlers this may be your google.com account, for others it is an angular.io account.
+
+In this project we have a number of Windows VMs running, each of them with several agents.
+The `provision-windows-buildkite.ps1` file contains instructions on how to create new host VMs that
+are fully configured to run the BuildKite agents as services.
+
+Our pipeline uses [docker-buildkite-plugin](https://github.com/buildkite-plugins/docker-buildkite-plugin)
+to run build steps inside docker containers.
+This way we achieve isolation and hermeticity.
+
+The `Dockerfile` file describes a custom Docker image that includes NodeJs, Yarn, and the Bazel 
+pre-requisites on Windows.
+
+To upload a new version of the docker image, follow any build instructions in `Dockerfile` and then
+run `docker build -t angular/node-bazel-windows:NEW_VERSION`, followed by 
+`docker push angular/node-bazel-windows:NEW_VERSION`. 
+After being pushed it should be available online, and you can use the new version in `pipeline.yml`.
+
+
+## Caretaker 
+
+BuildKite status can be found at https://www.buildkitestatus.com/.
+
+Issues related to the BuildKite setup should be escalated to the Tools Team via the current 
+caretaker, followed by Alex Eagle and Filipe Silva.
+
+Support requests should be submitted via email to support@buildkite.com and cc Igor, Misko, Alex,
+Jeremy and Manu
+
+
+## Rollout strategy
+
+At the moment our BuildKite CI uses 1 host VM running 4 agents, thus being capable of 4 concurrent 
+builds.
+The only test running is `bazel test //tools/ts-api-guardian:all`, and the PR check is not 
+mandatory.
+
+In the future we should add cache support to speed up the initial `yarn` install, and also Bazel
+remote caching to speed up Bazel builds.
+
+After the current setup is verified as stable and reliable the GitHub PR check can become mandatory.
+
+The tests ran should also be expanded to cover most, if not all, of the Bazel tests.
