-**Note:** The `--workdir` flag is only needed when your system disk is small but you have larger mounted storage (NFS, SAN, etc.). For standard deployments, it's not required.
+**Note:** 
+- The `--workdir` flag is only needed when your system disk is small but you have larger mounted storage (NFS, SAN, etc.)
+- The `--clean-cluster` flag drops all user databases before restore (keeps postgres, template0, template1). Use for disaster recovery scenarios.
 
 **Safety Features:**
