# Lyrion Music Server

Stream music to Squeezebox devices, the Squeezer Android/iOS app, and Chromecast.
Formerly known as Logitech Media Server (LMS).

- Web UI: http://localhost:9000
- Player port: 3483 (Squeezeboxes / apps)
- CLI port: 9090
- Music folder (read-only): \`$MUSIC_PATH\` → mounted at /music
- App data: \`config/\` and \`playlists/\`

## Manage
\`\`\`bash
cd $LYRION_DIR
docker compose up -d      # start
docker compose down       # stop
docker compose logs -f    # logs
docker compose pull && docker compose up -d   # update
\`\`\`

## Notes
- Uses \`network_mode: host\` so UDP discovery for Chromecast and Squeezebox devices
  works without manual port mapping.
- Change the music path in \`.env\` (\`MUSIC_PATH=\`), then \`docker compose up -d\`.
- Add music libraries in the web UI under Settings → Music Library.
