+# agones-bot Github Notification Bot
+
+This is the bot that created comments on GitHub pull requests whenever a
+[Google Cloud Build](https://cloud.google.com/build) build passes or fails.
+
+## Setup
+
+### Image
+
+Run `make build` to submit the cloud build to create the image that will be hosted on
+[Cloud Run](https://cloud.google.com/run).
+
+### Secrets
+
+It is expected that there will be a secret named `agones-bot-pr-commenter` with a 
+[Github auth token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) stored
+in it, and `agones-bot-pr-commenter@agones-images.iam.gserviceaccount.com` has the
+role `roles/secretmanager.secretAccessor` for the `gh-token` secret.
+
+### Deployment
+
+Run `make deploy` to copy the config to the appropriate bucket, and deploy the notifier image to Cloud Run.
+
+### Connect to Cloud Build
+
+Follow https://cloud.google.com/build/docs/subscribe-build-notifications to create the
+[Google Cloud PubSub topics](https://cloud.google.com/pubsub) for Google Cloud Build. 
+
+Follow https://cloud.google.com/run/docs/triggering/pubsub-push to setup the Notifier service to be triggered from
+PubSub with the `cloud-builds` pubsub topic.
