Description Sönke Schwardt-Krummrich

In larger UCS@school environments, new UCS@school slaves have to be installed but the DC master is not using the latest version of UCS@school (on purpose).
This might be a problem because the slave would get a newer/incompatible version of UCS@school than the DC master and the app center is currently only able to install the latest version.

A workaround might be univention-add-app/univention-app. We should add a short section to the administrator's manual.

Currently I'm in discussion with Dirk about some details.

Got feedback from Dirk:

univention-add-app is deprecated and will be removed somewhere in the future. 
So the documentation should use univention-add app. The neccessary commands are shown below. univention-run-join-scripts is currently required but will be integrated in univention-app later on.

+			Im Anschluss kann mit der webbasierten Konfiguration fortgefahren werden, wie sie in
