+# Migration Guide: Reorganizing Download Structure
+
+This guide is for upgrading from the old download structure to the new unified structure.
+
+## Old Structure
+```
+./downloads/     # Permanent downloads
+./kept/          # Favorited tracks  
+./cache/         # Cached tracks
+```
+
+## New Structure
+```
+./downloads/
+├── permanent/   # Permanent downloads
+├── kept/        # Favorited tracks
+└── cache/       # Cached tracks
+```
+
+## Migration Steps
+
+### 1. Stop the Container
+```bash
+docker-compose down
+```
+
+### 2. Backup Your Data (Recommended)
+```bash
+# Create a backup
+tar -czf allstarr-backup-$(date +%Y%m%d).tar.gz downloads/ kept/ cache/ 2>/dev/null
+```
+
+### 3. Create New Directory Structure
+```bash
+mkdir -p downloads/permanent downloads/kept downloads/cache
+```
+
+### 4. Move Existing Files
+
+**Move permanent downloads:**
+```bash
+# If you have files directly in downloads/
+if [ -d "downloads" ] && [ ! -d "downloads/permanent" ]; then
+  # Move all files/folders except the new subdirectories
+  find downloads/ -maxdepth 1 -mindepth 1 ! -name 'permanent' ! -name 'kept' ! -name 'cache' ! -name 'playlists' -exec mv {} downloads/permanent/ \;
+fi
+
+# Move playlists folder if it exists
+if [ -d "downloads/playlists" ]; then
+  mv downloads/playlists downloads/permanent/
+fi
+```
+
+**Move kept files:**
+```bash
+if [ -d "kept" ]; then
+  mv kept/* downloads/kept/ 2>/dev/null || true
+  rmdir kept
+fi
+```
+
+**Move cache files:**
+```bash
+if [ -d "cache" ]; then
+  mv cache/* downloads/cache/ 2>/dev/null || true
+  rmdir cache
+fi
+```
+
+### 5. Update .env File
+```bash
+# Remove old variables
+sed -i.bak '/^KEPT_PATH=/d' .env
+sed -i.bak '/^CACHE_PATH=/d' .env
+
+# Ensure DOWNLOAD_PATH is set correctly
+if ! grep -q "^DOWNLOAD_PATH=" .env; then
+  echo "DOWNLOAD_PATH=./downloads" >> .env
+else
+  sed -i.bak 's|^DOWNLOAD_PATH=.*|DOWNLOAD_PATH=./downloads|' .env
+fi
+```
+
+### 6. Update Media Server Library Paths
+
+**For Jellyfin:**
+1. Go to Dashboard → Libraries
+2. Edit your Music library
+3. Update the folder path from `downloads` to `downloads/permanent`
+4. Scan library
+
+**For Navidrome/Subsonic:**
+1. Update your music folder configuration
+2. Change from `downloads` to `downloads/permanent`
+3. Restart and rescan
+
+### 7. Verify Migration
+```bash
+# Check the new structure
+ls -la downloads/
+ls -la downloads/permanent/
+ls -la downloads/kept/
+ls -la downloads/cache/
+
+# Count files in each directory
+echo "Permanent: $(find downloads/permanent -type f | wc -l) files"
+echo "Kept: $(find downloads/kept -type f | wc -l) files"
+echo "Cache: $(find downloads/cache -type f | wc -l) files"
+```
+
+### 8. Start the Container
+```bash
+docker-compose up -d
+```
+
+### 9. Check Logs
+```bash
+docker-compose logs -f allstarr
+```
+
+## Rollback (If Needed)
+
+If something goes wrong:
+
+```bash
+# Stop container
+docker-compose down
+
+# Restore from backup
+tar -xzf allstarr-backup-YYYYMMDD.tar.gz
+
+# Restore old .env
+mv .env.bak .env
+
+# Start container
+docker-compose up -d
+```
+
+## Verification Checklist
+
+- [ ] All files moved to new structure
+- [ ] Old directories removed or empty
+- [ ] .env file updated
+- [ ] Media server library paths updated
+- [ ] Container starts without errors
+- [ ] Can play existing tracks
+- [ ] New downloads go to correct folders
+- [ ] Favoriting external tracks works
+- [ ] Cache cleanup works
+
+## Notes
+
+- The migration preserves all your existing files
+- Playlists (.m3u files) are moved to `downloads/permanent/playlists/`
+- Relative paths in M3U files should still work
+- If you have a lot of files, the migration may take a few minutes
+- The backup is optional but highly recommended

 #### How It Works
 
-1. **Spotify Import Plugin Runs** (e.g., daily at 4:15 PM)
+1. **Spotify Import Plugin Runs**
    - Plugin fetches your Spotify playlists
    - Creates/updates playlists in Jellyfin with tracks already in your library
    - Generates "missing tracks" JSON files for songs not found locally
-   - Files are named like: `Release Radar_missing_2026-02-01_16-15.json`
 
-2. **Allstarr Fetches Missing Tracks** (within sync window)
+2. **Allstarr Matches Tracks** (on startup + every 24 hours by default)
-   - Searches for missing tracks files from the Jellyfin plugin
+   - Reads missing tracks files from the Jellyfin plugin
-   - Searches **+24 hours forward first** (newest files), then **-48 hours backward** if not found
-   - This efficiently finds the most recent file regardless of timezone differences
-   - Example: Server time 12 PM EST, file timestamped 9 PM UTC (same day) → Found in forward search
-   - Caches the list of missing tracks in Redis + file cache
-   - Runs automatically on startup (if needed) and every 5 minutes during the sync window
-
-3. **Allstarr Matches Tracks** (2 minutes after startup, then configurable interval)
    - For each missing track, searches your streaming provider (SquidWTF, Deezer, or Qobuz)
    - Uses fuzzy matching to find the best match (title + artist similarity)
    - Rate-limited to avoid overwhelming the service (150ms delay between searches)
-   - Caches matched results for 1 hour
+   - Pre-builds playlist cache for instant loading
-   - **Pre-builds playlist items cache** for instant serving (no "on the fly" building)
-   - Default interval: 24 hours (configurable via `SPOTIFY_IMPORT_MATCHING_INTERVAL_HOURS`)
-   - Set to 0 to only run once on startup (manual trigger via admin UI still works)
 
-4. **You Open the Playlist in Jellyfin**
+3. **You Open the Playlist in Jellyfin**
    - Allstarr intercepts the request
    - Returns a merged list: local tracks + matched streaming tracks
-   - Loads instantly from cache (no searching needed!)
+   - Loads instantly from cache!

 ```
 
-#### Startup Behavior
+#### Web UI Management
 
-When Allstarr starts with Spotify Import enabled:
+The easiest way to manage Spotify playlists is through the Web UI at `http://localhost:5275`:
 
-**Smart Cache Check:**
+1. **Link Playlists Tab**: Link Jellyfin playlists to Spotify playlists
-- Checks if today's sync window has passed (e.g., if sync is at 4 PM + 2 hour window = 6 PM)
+2. **Active Playlists Tab**: View status, trigger matching, and manage playlists
-- If before 6 PM and yesterday's cache exists → **Skips fetch** (cache is still current)
+3. **Configuration Tab**: Enable/disable Spotify Import and adjust settings
-- If after 6 PM or no cache exists → **Fetches missing tracks** from Jellyfin plugin
-
-**Track Matching:**
-- **T+2min**: Matches tracks with streaming provider (with rate limiting)
-- Only matches playlists that don't already have cached matches
-- **Result**: Playlists load instantly when you open them!
-
-**Example Timeline:**
-- Plugin runs daily at 4:15 PM, creates files at ~4:16 PM
-- You restart Allstarr at 12:00 PM (noon) the next day
-- Startup check: "Today's sync window ends at 6 PM, and I have yesterday's 4:16 PM file"
-- **Decision**: Skip fetch, use existing cache
-- At 6:01 PM: Next scheduled check will search for new files
 
 #### Troubleshooting
 
 **Playlists are empty:**
 - Check that the Spotify Import plugin is running and creating playlists
-- Verify `SPOTIFY_IMPORT_PLAYLIST_IDS` match your Jellyfin playlist IDs
+- Verify playlists are linked in the Web UI
 - Check logs: `docker-compose logs -f allstarr | grep -i spotify`
 
 **Tracks aren't matching:**
 - Ensure your streaming provider is configured (`MUSIC_SERVICE`, credentials)
-- Check that playlist names in `SPOTIFY_IMPORT_PLAYLIST_NAMES` match exactly
+- Manually trigger matching via Web UI or API
-- Manually trigger matching: `curl "https://your-proxy.com/spotify/match?api_key=KEY"`
+- Check that the Jellyfin plugin generated missing tracks files
 
-**Sync timing issues:**
+**Performance:**
-- Set `SPOTIFY_IMPORT_SYNC_START_HOUR/MINUTE` to match your plugin schedule
+- Matching runs in background with rate limiting (150ms between searches)
-- Increase `SPOTIFY_IMPORT_SYNC_WINDOW_HOURS` if files aren't being found
+- First match may take a few minutes for large playlists
-- Check Jellyfin plugin logs to confirm when it runs
+- Subsequent loads are instant (served from cache)
 
 #### Notes
 
-- This feature uses your existing `JELLYFIN_URL` and `JELLYFIN_API_KEY` settings
+- Uses your existing `JELLYFIN_URL` and `JELLYFIN_API_KEY` settings
-- Matched tracks are cached for 1 hour to avoid repeated searches
+- Matched tracks cached for fast loading
-- Missing tracks cache persists across restarts (stored in Redis + file cache)
+- Missing tracks cache persists across restarts (Redis + file cache)
-- Rate limiting prevents overwhelming your streaming provider (150ms between searches)
+- Rate limiting prevents overwhelming your streaming provider
 - Only works with Jellyfin backend (not Subsonic/Navidrome)

+**Storage modes:**
+- **Permanent** (`downloads/permanent/`): Files saved permanently and registered in your media server
+- **Cache** (`downloads/cache/`): Temporary files, auto-cleaned after `CACHE_DURATION_HOURS`
+- **Kept** (`downloads/kept/`): External tracks you've favorited - always permanent, separate from cache
