-In order to persist your data, you need to mount a docker volume or create a host bind-mount at `/var/lib/ocis`, for example with: `-v /some/host/dir:/var/lib/ocis`
+We are using named volumes for the oCIS configuration and oCIS data in the above example (`-v ocis-config:/etc/ocis -v ocis-data:/var/lib/ocis`). You could instead also use host bind-mounts instead, eg. `-v /some/host/dir:/var/lib/ocis`.
 
 You cannot use bind mounts on MacOS, since extended attributes are not supported ([owncloud/ocis#182](https://github.com/owncloud/ocis/issues/182), [moby/moby#1070](https://github.com/moby/moby/issues/1070)).
