+# Cloud Build Google Chat Notifier
+
+This notifier uses [Google Chat Webhooks](https://developers.google.com/chat/how-tos/webhooks) to
+send notifications to your Google Chat space.
+
+This notifier runs as a container via Google Cloud Run and responds to
+events that Cloud Build publishes via its
+[Pub/Sub topic](https://cloud.google.com/cloud-build/docs/send-build-notifications).
+
+For detailed instructions on setting up this notifier,
+see [Configuring Google Chat notifications](https://cloud.google.com/cloud-build/docs/configuring-notifications/configure-googlechat).
+
+## Configuration Variables
+
+This notifier expects the following fields in the `delivery` map to be set:
+
+- `webhook_url`: The `secretRef: <GoogleChat-webhook-URL>` map that references the
+Slack webhook URL resource path in the `secrets` section.
