 ## Usage
 
-### GUI Application
-
-Launch the graphical interface:
-
 ```bash
-navipod-gui
-```
-
-The GUI provides:
-- Input fields for Navidrome URL, username, and password
-- Firmware type selector (Stock/Rockbox)
-- Mount point browser
-- Real-time sync status and progress
-- Error display
-
-### Command Line
-
-```bash
-# Sync all configured content
-navipod sync
+# Sync all configured content (with progress bar)
+cargo run -- sync
 
 # Sync specific album
-navipod sync --album "Album Name"
+cargo run -- sync --album "Album Name"
+
+# Sync specific artist
+cargo run -- sync --artist "Artist Name"
 
 # List available albums
-navipod list-albums
+cargo run -- list-albums
 
 # Check iPod connection
-navipod check
+cargo run -- check
+
+# Scrobble listening history to ListenBrainz
+cargo run -- scrobble
+
+# Scrobble and clear the log (with backup)
+cargo run -- scrobble --clear
+
+# Scrobble and clear without backup
+cargo run -- scrobble --clear --no-backup
 ```
 
+### Scrobbling to ListenBrainz
+
+NaviPod can read the `.scrobbler.log` file from your Rockbox iPod and submit your listening history to ListenBrainz:
+
+1. Get your ListenBrainz user token from https://listenbrainz.org/profile/
+2. Add it to your `config.toml`:
+   ```toml
+   [listenbrainz]
+   token = "your_token_here"
+   ```
+3. Run the scrobble command:
+   ```bash
+   cargo run -- scrobble --clear
+   ```
+
+The `--clear` flag will remove the scrobbler log after successful submission (with automatic backup).
+This is useful to avoid re-submitting the same listens next time.
+

-1. Make sure you're in `nix-shell` (it provides all necessary libraries)
-2. The GUI will automatically use X11 if Wayland is not available
