 **Why bind mounts?** Bind mounts put files in a known place on the host. You can edit `config.yaml` with any editor, inspect logs, or wipe the data directory without going through Docker commands.
 
-### Linux: ownership
-
-The container runs as a non-root user (UID `64198`). On Linux with bind mounts, pre-create the directories with the correct owner before starting the container:
-
-```bash
-mkdir -p config data
-chown -R 64198:64198 config data
-```
-
-Docker Desktop on Mac and Windows handles this automatically.

 ### Named volumes (alternative)
 
 If you prefer Docker-managed storage, named volumes work too — replace the bind mounts:
