## Documentation

- [Music For Programming](mfp.md) - Primary content integration
- [Chapter Files](chapters.md) - FFmpeg format and CUE conversion
- [Installation](installation.md) - Setup mpv and dependencies
- [tmux Status Line](tmux-status.md) - Show current track in tmux
- [IPC Reference](ipc.md) - Raw socket commands

## Configuration

Set default startup volume in `~/.voicemode/voicemode.env`:

```bash
VOICEMODE_DJ_VOLUME=50   # Default: 50%
```

The DJ starts at 50% volume by default, which works well during voice conversations.

## History & Favorites

### Play History

Tracks played from the indexed music library are recorded:

```bash
voicemode dj history            # Show last 20 plays
voicemode dj history --limit 50 # Show last 50 plays
```

History is stored in the music library database (`~/.voicemode/dj/library.db`).

### Favorites

Toggle favorite status on the currently playing track:

```bash
voicemode dj favorite    # Toggle favorite on current track
voicemode dj find "*"    # Favorites marked with *
```

Note: History and favorites require tracks to be indexed in the music library.
Run `voicemode dj library scan` to index your music folder first.
