    - Go to Jellyfin Dashboard → Plugins → Spotify Import

-   - Set a daily sync schedule (e.g., 4:15 PM daily)
+   - Set a sync schedule (the plugin will create playlists in Jellyfin)
-   - The plugin will create playlists in Jellyfin and generate "missing tracks" files for songs not in your library
 
 3. **Configure Allstarr**

+   - Uses your existing `JELLYFIN_URL` and `JELLYFIN_API_KEY` settings
 
 #### Configuration
 
 | Setting | Description |
 |---------|-------------|
 | `SpotifyImport:Enabled` | Enable Spotify playlist injection (default: `false`) |
-| `SpotifyImport:SyncStartHour` | Hour when the Spotify Import plugin runs (24-hour format, 0-23) |
+| `SpotifyImport:MatchingIntervalHours` | How often to run track matching in hours (default: 24, set to 0 for startup only) |
-| `SpotifyImport:SyncStartMinute` | Minute when the plugin runs (0-59) |
+| `SpotifyImport:Playlists` | JSON array of playlists (managed via Web UI) |
-| `SpotifyImport:SyncWindowHours` | Hours to search for missing tracks files after sync time (default: 2) |
-| `SpotifyImport:PlaylistIds` | Comma-separated Jellyfin playlist IDs to intercept |

 # Enable the feature

 #### 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!
 
-5. **You Play a Track**

+   - Local tracks stream from Jellyfin normally

 ```
 
-#### 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)
