 - ReInstall:

 - Destroy
 `jailman.sh -d $jailname`
+Example:
+`jailman.sh -d sonarr`

+You can also do multiple jails in one pass:
+Example:
+`jailman.sh -i sonarr radarr lidarr`
 
 This installs the jail, creates the config dataset if needed, installs all packages and sets them up for you.
 Only thing you need to do is do the setup of the packages in their respective GUI.
