 The app uses Wolfskin launcher artwork and a lilac-on-`#07070a` theme by default on a fresh install. Existing theme choices and all upstream colour themes remain available under Settings → App theme. Settings → About credits and links to Wholphin by damontecres.
 
+## Wolfskin TV updates
+
+Settings opens on Requests. Press Down, then OK to open Updates; the row and screen show the installed app version. Left/Right selects an action, Down reaches Auto-check, and Up returns to the remembered action. Release notes keep focus inside the notes panel: Up/Down scrolls, and Back returns to the Release notes button.
+
+Auto-check uses the same preference as classic settings and only checks for updates. Manual checks remain available when it is off. Download and Install update are separate, explicit actions; Android owns installation permission and confirmation. Returning from Android refreshes the installed version. Back can leave a download running, and returning to Updates shows the controller's current state.
+
+Classic settings (trial) is the final Settings row. It opens the full original settings, including About → Update and More/Advanced → Updates. All existing settings groups remain available.
