+# This workflow will deploy source code on Cloud Run when a commit is pushed to the "master" branch
+#
+# Overview:
+#
+# 1. Authenticate to Google Cloud
+# 2. Deploy it to Cloud Run
+#
+# To configure this workflow:
+#
+# 1. Ensure the required Google Cloud APIs are enabled:
+#
+#    Cloud Run            run.googleapis.com
+#    Cloud Build          cloudbuild.googleapis.com
+#    Artifact Registry    artifactregistry.googleapis.com
+#
+# 2. Create and configure Workload Identity Federation for GitHub (https://github.com/google-github-actions/auth#setting-up-workload-identity-federation)
+#
+# 3. Ensure the required IAM permissions are granted
+#
+#    Cloud Run
+#      roles/run.admin
+#      roles/iam.serviceAccountUser     (to act as the Cloud Run runtime service account)
+#
+#    Cloud Build
+#      roles/cloudbuild.builds.editor
+#
+#    Cloud Storage
+#      roles/storage.objectAdmin
+#
+#    Artifact Registry
+#      roles/artifactregistry.admin     (project or repository level)
+#
+#    NOTE: You should always follow the principle of least privilege when assigning IAM roles
+#
+# 4. Create GitHub secrets for WIF_PROVIDER and WIF_SERVICE_ACCOUNT
+#
+# 5. Change the values for the SERVICE and REGION environment variables (below).
