+# 🚀 Quick Start: Offline Playlists
+
+## For Users
+
+### Download Playlist for Offline Use:
+1. Navigate to any playlist
+2. Scroll to "Cache for Offline" card
+3. Tap **"Make Available Offline"**
+4. Wait for download to complete
+5. Green checkmark = Ready! 🎉
+
+### Play Offline:
+1. Enable airplane mode
+2. Open SoundWave
+3. Navigate to cached playlist
+4. Tap Play - Works instantly! 📱
+
+### Manage Storage:
+1. Tap **"Offline"** in sidebar (PWA badge)
+2. View all cached playlists
+3. Remove individual playlists or clear all
+4. See storage usage at a glance
+
+---
+
+## For Developers
+
+### Check if Playlist is Cached:
+```typescript
+import { offlineStorage } from '../utils/offlineStorage';
+
+const playlist = await offlineStorage.getPlaylist(id);
+if (playlist?.offline) {
+  console.log('Available offline!');
+}
+```
+
+### Cache a Playlist:
+```typescript
+import { usePWA } from '../context/PWAContext';
+
+const { cachePlaylist } = usePWA();
+const audioUrls = tracks.map(t => `/api/audio/${t.youtube_id}/download/`);
+
+await cachePlaylist(playlistId, audioUrls);
+await offlineStorage.savePlaylist({...playlist, offline: true});
+```
+
+### Remove from Cache:
+```typescript
+const { removePlaylistCache } = usePWA();
+
+await removePlaylistCache(playlistId, audioUrls);
+await offlineStorage.removePlaylist(id);
+```
+
+---
+
+## New Routes
+
+- `/offline` - Offline storage management page
+- All existing routes unchanged
+
+---
+
+## Security ✅
+
+- ✅ Authentication required for all endpoints
+- ✅ User isolation enforced (owner-based filtering)
+- ✅ No cross-user data access
+- ✅ Service Worker respects authentication
+- ✅ No route conflicts
+
+---
+
+## Testing
+
+### Online:
+```bash
+# Navigate to playlist, click "Make Available Offline"
+# Check sidebar badge shows "Offline" menu
+# Visit /offline to see cached playlists
+```
+
+### Offline:
+```bash
+# Enable airplane mode in browser DevTools
+# Navigate to cached playlist
+# Verify playback works
+# Check offline warning appears for uncached content
+```
+
+---
+
+## Browser DevTools Testing
+
+### Service Worker:
+```
+Application → Service Workers → soundwave-v1 (Active)
+```
+
+### Cache Storage:
+```
+Application → Cache Storage
+- soundwave-audio-v1 (audio files)
+- soundwave-api-v1 (API responses)
+```
+
+### IndexedDB:
+```
+Application → IndexedDB → soundwave-offline
+- playlists (cached metadata)
+```
+
+---
+
+## Storage Limits
+
+- **Desktop**: ~50% of available disk space
+- **Mobile**: ~50% of available storage
+- **Minimum**: 10 MB per origin
+- **Typical**: Several GB available
+
+---
+
+## Known Behaviors
+
+1. **Storage is per-browser** - Not synced across devices
+2. **Caching requires network** - Must be online to download
+3. **Authentication required** - Token must be valid
+4. **Browser may evict** - On low storage, browser clears cache
+5. **HTTPS required** - Service Workers need secure context
