+## Work Pools
 
-Workers are deployed separately with their own docker-compose. Flow-specific secrets (S3 credentials, API keys, etc.) should be managed via **Prefect Blocks**, not environment variables.
+The `prefect-worker-pg-backup` service automatically creates and listens to the `pg-backup-pool` work pool (type: process).
