Current intallation of peertube on Ubuntu 18.04

I’m looking for good current installation instructions for Peertube on Ubuntu server 18.04, I have found documentation but it is typically poorly written assuming you are a admin of some type, using incomplete command structure to install, can any one assist, I’m not a complete idiot but would like complete dummy proof instructions.

Maybe you can try the actuel documentation and improve it yourself by telling peertube devs what is wrong and/or what is not clear ?
