+The container publishes Roundcube on host port `9002`. SMTP uses port `587` by default and the `tls://` server prefix, which makes Roundcube negotiate STARTTLS. Its database is retained in the named `roundcube-db` volume.
+
+## Skins
+
+Set `ROUNDCUBE_SKIN` in `.env` to choose the UI skin (default `elastic`). The image bundles `elastic` and `larry`; any other skin published as `roundcube/<name>` on Packagist (for example `roundcube/larry`) is installed automatically on container start. Because the web root is bind-mounted at `./var/www`, installed skins persist across container recreations.
+
+To use a custom third-party skin, drop its folder into `./var/www/html/skins/` and set `ROUNDCUBE_SKIN` to the folder name. Signed-in users can also pick any installed skin themselves under Settings → Preferences → User Interface.
