Help with running Emby on Nethserver 7

I followed some of the docs/howtos related to install UniFi managament server on a Linux server

then I added all the steps for “nethifi” the setup a bit.
Not as good as been done here…

But… it helped a bit.
UniFi requires some other linux components (Java, mongodb).

Getting back to Emby…
I hope that the project explain “how it works, and how it’s connected to Linux”, so a skilled enough linux guy could be able do “adapt” it to his enviroment.
NethServer lays over Centos, but into development documentation is explained how. I were not able to find it for Emby on the site… after a quick search, i had to admit.
