+which enables automatic switching between two user-defined (customizable)
+themes.  This transition occurs seamlessly in response to dark mode being
+enabled or disabled in the desktop preferences (such as in GNOME).  It uses
+DBus to query the system configured value.  To enable it, put the following
+snippet to your Emacs configuration file:
+@lisp
+(require auto-dark)
+(auto-dark-mode t)
+@end lisp
+To customize the themes used, visit @samp{M-x customize-group auto-dark}.")
