+# Spotify Tracker Deployment Guide
+
+## Quick Setup
+
+1. **Clone and deploy:**
+   ```bash
+   git clone <your-repo-url>
+   cd spotify-tracker
+   chmod +x deploy.sh
+   sudo ./deploy.sh
+   ```
+
+2. **Configure Caddy:**
+   ```
+   spotify.tougie.live {
+     reverse_proxy localhost:8888
+   }
+   ```
+
+3. **Update Spotify App Settings:**
+   - Go to https://developer.spotify.com/dashboard
+   - Set redirect URI to: `https://spotify.tougie.live`
+
+## Service Management
+
+```bash
+# Check service status
+sv status spotify-tracker
+
+# Start/stop/restart service  
+sv start spotify-tracker
+sv stop spotify-tracker
+sv restart spotify-tracker
+
+# View logs
+tail -f /var/log/spotify-tracker/current
+```
+
+## API Endpoints
+
+After deployment, these endpoints will be available:
+
+- `https://spotify.tougie.live/auth` - OAuth setup page
+- `https://spotify.tougie.live/current` - Current track (JSON)
+- `https://spotify.tougie.live/phantombot` - Current track (text for PhantomBot)
+- `https://spotify.tougie.live/health` - Health check
+
+## Configuration
+
+The service runs as user `spotify-tracker` and stores:
+- Config: `/home/spotify-tracker/.config/spotify-tracker/`
+- Logs: `/var/log/spotify-tracker/`
+- Binary: `/opt/spotify-tracker/target/release/spotify-tracker`
+
+## Troubleshooting
+
+1. **Check service status:** `sv status spotify-tracker`
+2. **View logs:** `tail -f /var/log/spotify-tracker/current`
+3. **Restart service:** `sv restart spotify-tracker`
+4. **Check permissions:** Ensure `spotify-tracker` user owns `/opt/spotify-tracker`
