Jibri installation

I want to install and configure recording of meetings in jitsi.
Found 2 documents and not sure which one is most up to date?
I have an ubuntu 18.04 and the latest jitsi stable on my machine.

I don’t like the first youtube video, because I don’t want to replace my current linux image.
The second, Readme of jibri repo mentions ubuntu 16, but I have 18.
So does this mean I won’t be able to install it on 18?

Maybe there is another tutorial that explains how to install/config jibri on ubuntu 18?

Thank you.
