-### Required parameters
-
-#### Mailcow data directory: -d _/path/to/data/_
-
-This is the full path to the location where Mailcow actually stores data.  In
-a setup such as I recommend on my blog at
-[https://mytechiethoughts.com](https://www.mytechiethoughts.com), you would be
-using an entry such as *'/var/nc_data'*.  This directory and all subdirectories
-are automatically included in the backup.
-
-#### Mailcow webroot: -n _/path/to/Mailcow/_
-
-This is the directory in which Mailcow's php and html files are located.  It
-is generally somewhere under your webroot directory.  This is required so the
-script can find the 'OCC' command to invoke maintenance mode.
-
-#### webuser account: -w _accountName_
-
-This is the account that Mailcow runs under via your webserver.  This is
-almost always *'www-data'*.  You would have to check your NGINX/Apache config to
-be sure.  'OCC' will not run as any other user thus, the script cannot
-enter/exit maintenance mode without knowing which user to emulate.
-
 ### Optional parameters
 
 #### Path to 503 error page: -5 _/path/to/filename.html_
