-${ORANGE}DESCRIPTION${RESET}
-    This is the main administration script that you use for all interactions with your
-    mail server. Setup, configuration and much more is done with this script.
-
-    Please note that the script executes most of the commands inside the container itself.
-    If the image was not found, this script will pull the ${WHITE}:latest${RESET} tag of
-    ${WHITE}mailserver/docker-mailserver${RESET}. This tag refers to the latest release,
-    see the tagging convention in the README under
-    ${BLUE}https://github.com/docker-mailserver/docker-mailserver/blob/master/README.md${RESET}
-
-    You will be able to see detailed information about the script you're invoking and
-    its arguments by appending ${WHITE}help${RESET} after your command. Currently, this
-    does not work with all scripts.
-
-${ORANGE}VERSION${RESET}
-    The current version of this script is backwards compatible with versions of
-    ${WHITE}docker-mailserver${RESET} ${BOLD}after${RESET} ${BLUE}8.0.1${RESET}. In case that there is not a more recent release,
-    this script is currently only working with the ${WHITE}:edge${RESET} tag.
-
-    You can download the script for your release by substituting TAG from the
-    following URL, where TAG looks like 'vX.X.X':
