+# Permission
+If Nextcloud data is being placed in a docker managed volume, then `Dockerfile` can be updated by removing L6-L10 thus making the image smaller and not modifying the permissions for Nextcloud.  
+If Nextcloud data should be accessible from "bare metal system" as a specific user, then modify `Dockerfile` with correct `UID` and `GID` values.
