+        Blueman applet.
+
+        Note, for the applet to work, 'blueman' package should also be installed system-wide
+        since it requires running 'blueman-mechanism' service activated via dbus.
+        You can add it to the dbus packages in system configuration:

+          services.dbus.packages = [ pkgs.blueman ];
+      '';
