+# Config
+
+The app service currently defaults to Google Cloud Run as a provider. In future it will support more. 
+This requires setting up a config key `app` with service accounts and related info. See handler/google.go 
+to understand what is required. Additionally we require a dummy service account with no permissions 
+for the deployed apps.
