+    # Use the GitHub API to make an authenticated call that triggers a workflow
+    # in the manifests repository. The targeted workflow opens a PR to use the
+    # new image that was pushed to quay.io. A personal access token (PAT) is
+    # required to make the API call. The PAT can be created by a member of the
+    # redhat-developer-demos org by visiting https://github.com/settings/personal-access-tokens/new
+    # and selecting "redhat-developer-demos" under resource owner dropdown.
+    # Select the rps repositories, and then add actions read/write permissions
+    # 
+    # Set the PAT_TOKEN at https://github.com/redhat-developer-demos/rps-game/settings/secrets/actions
+    # 
+    # You can manually trigger the action using curl
+    # curl -X POST \
+    # -H "Authorization: Bearer $PAT" \
