+## Register mydm as a system service
+
+Making mydm a system service is often useful. Before this feature is developed, if a user want to let mydm boot automatically start, he had to mydm complete start command written in such a file like `/etc/rc.local`
+
+Now, the good news comes, mydm can be installed as a system service. The mydm suite now comes with a script called `mydm-service-install` that allows users to automate installation services on their own systems.
+
+> mydm-service-install now only used in a LSB-supported initialization system. Development of other initialization systems is under way.
