+## autoshutdown mod
+
+Allows admins to schedule a shutdown when the last player leaves.
+
+The server shuts down a little time after the last player leaves,
+to make sure all areas are slowly unloaded.
+
+To schedule an automatic shutdown, issue the `/autoshutdown` command
+in chat. The shutdown will only happen once.
