+## Implementation Status
+
+**Current Status:** ✅ **Phase 1 (MVP) - COMPLETE**
+
+**Last Updated:** 2025-12-12
+
+### Phase 1 (MVP) - ✅ COMPLETE
+
+All Phase 1 features have been implemented and are fully functional:
+
+| Feature | Status | Implementation Notes |
+|---------|--------|---------------------|
+| Bot auto-join | ✅ Complete | Bot automatically joins configured voice channel on startup |
+| Continuous playback | ✅ Complete | Loops through all MP3s in music directory, reloads library when empty |
+| Now playing display | ✅ Complete | Web UI shows track title, artist, duration with real-time progress bar |
+| Skip track | ✅ Complete | Working skip button with WebSocket notification |
+| Pause/Resume | ✅ Complete | Full pause/resume functionality with state persistence |
+| Track list | ✅ Complete | Full library display with track metadata, duration, and file size |
+| MP3 upload | ✅ Complete | Drag-and-drop upload with validation, progress, and batch support |
+| Volume control | ✅ Complete | Real-time volume adjustment (0-100%) with visual slider |
+| Shuffle mode | ✅ Complete | Queue shuffling with toggle state |
+| Real-time updates | ✅ Complete | WebSocket connection for live playback state changes |
+
+**Technology Stack Chosen:**
+- **Bot Service:** Node.js + discord.js + @discordjs/voice
+- **API Backend:** Node.js + Express + ws (WebSocket) + multer + music-metadata
+- **Web Frontend:** React 18 + Vite + Tailwind CSS
+- **Deployment:** Docker Compose with 3 services
+
+**Architecture Decisions:**
+- Bot-API Communication: HTTP Internal API (Option A from spec)
+- Music metadata: Extracted on upload and library scan using music-metadata
+- File upload: Multer with configurable size limits and duplicate handling
+- Real-time updates: WebSocket server with 2-second polling of bot state
+
+### Phase 2 - ⏳ NOT STARTED
+
+The following Phase 2 features are planned but not yet implemented:
+
+| Feature | Status | Notes |
+|---------|--------|-------|
+| Queue reordering | ⏳ Not started | Requires drag-and-drop UI and queue management in bot |
+| Search | ⏳ Not started | Filter/search tracks in library |
+| Track progress seek | ⏳ Not started | Seekable progress bar (discord.js limitation may apply) |
+| Album art | ⏳ Not started | Display embedded album art from MP3 metadata |
+| Previous track | ⏳ Not started | History tracking and previous button |
+
+**Challenges for Phase 2:**
+- Seek functionality may be limited by Discord.js voice implementation
+- Album art extraction and caching needs design
+- Queue reordering requires persistent queue state
+
+### Phase 3 - ⏳ NOT STARTED
+
+| Feature | Status | Notes |
+|---------|--------|-------|
+| Multi-channel support | ⏳ Not started | Multiple bots or channel switching |
+| User authentication | ⏳ Not started | Password protection for DJ interface |
+| Discord slash commands | ⏳ Not started | Control bot via Discord commands |
+| Listening history | ⏳ Not started | Requires database for logging |
+| Favorites/playlists | ⏳ Not started | Custom playlist management |
