 ## azk restart
 
-  Stops either all instances of the systems in the current `Azkfile.js` or the one specified and starts them back again. If an error occurs during reboot, all systems will be stopped.
+Restart works by memorizing the current status of the systems in the current `Azkfile`, stops them and then get them back online again.
+
+If a `[system]` is specified with the command, `azk` will just restart the specified system.

+To restart a system and its dependencies is necessary to pass a list of systems to be restarted: `azk restart system_dependency,system_top`.
