 This will use Apache as webserver on the host for new installation and whatever was already used for updates.

-In contrary to our hosting or trials, Rocket.Chat in an on premise installation requires several configuration steps in EGroupware and Rocket.Chat, see the separate chapter in this wiki.
+> Rocket.Chat is no longer installed by default, as for an automatic OAuth configuration we need to know the domain name EGroupware and Rocket.Chat are using.
