+@defvr {Scheme Variable} lightdm-service-type
+This is the type of the service to run the
+@url{https://github.com/canonical/lightdm,LightDM display manager}.  Its
+value must be a @code{lightdm-configuration} record, which is documented
+below.  Among its distinguishing features are TigerVNC integration for
+easily remoting your desktop as well as support for the XDMCP protocol,
+which can be used by remote clients to start a session from the login
+manager.
+
+In its most basic form, it can be used simply as:
+
+@lisp
+(service lightdm-service-type)
+@end lisp
+
+A more elaborate example making use of the VNC capabilities and enabling
+more features and verbose logs could look like:
+
+@lisp
+(service lightdm-service-type
+         (lightdm-configuration
+          (allow-empty-passwords? #t)
+          (xdmcp? #t)
