 **Note on networking:** This shell requires NetworkManager for WiFi functionality.
 
+**Note on system app theming:** DankMaterialShell can automatically theme GTK and Qt applications to match your dynamic wallpaper colors. This requires:
+- For GTK apps: `adw-gtk3` theme and `gsettings`
+- For Qt apps: `qt5ct` and/or `qt6ct`
+
+Enable these features in Settings → Appearance → System App Theming after installing the dependencies.

 3. Install DankMaterialShell
