Hi,
Yes, this demo is meant to cover the very basics and most important aspect of PUN.
However. Hold your horses. I am in talk with Exitgames, and I'll likely update this to use the new Unity UI system, which will be a lot better then a demo using the old UI.
So I think that as a first step, get acquainted with PUN, to understand it and get back to me when you are good to shoot your tutorial, I'll provide with a proper update on this.
And I am actually interested in your take and approach on explaining things, being french, it's tricky for me to find the right wordings, so I would actually be ok to either reword the wiki tutorial to match your explanations, or we could work on a new tutorial, together?
Bye,
Jean
