I’m replying myself, I just created a new space in bitbucket.org to be able to have some wiki stile documentation at hand and started moving some info there.
In the forums there is plenty of information, but sometimes is quite difficult to find (specially when using both the italian and the english forums)
With this space (http://bitbucket.org/aseques/zeroshell-documentation ) I would like to have a place to gather some documentation in a form it can stay up to date. If anyone wants to have write rights to the wiki just ask.
At the moment that there is another official place to do this function I’d be glad to move all the stuff to here
