How can I Install the Repetier-Server Beta Version and test latest features?

grep

I remember installing once a Repetier-Server beta, it was Linux only and there have been some simple terminal commands. Sadly I can't fine these commands anymore.
I only found the information for installing the official release, e.g. here:
Repetier-Server Manual

Can someone help me to switch to the Beta branch?

Repetier

On our pi you can run
installDev
to update to latest dev version. For nightly builds run
installRepetierNightly

For other linux versions see
https://www.repetier-server.com/knowledgebase/nightly_builds/<br/><br/>They only have nightly build which is dev just updated only once per day.
