WELCOME_MSG="\
Welcome to grommunio Setup.

grommunio Setup helps setting up grommunio and get it up and running.
During the installation, grommunio Setup will modify system settings.

Make sure that, before running grommunio Setup, you have a working Internet
connection. This is needed to access online software repositories
and create TLS certificates using Let's Encrypt.

You can always abort grommunio Setup by pressing the \"ESC\" key.

For more information, refer to https://docs.grommunio.com/admin"
