I was working on a project where a Wiki was used for dokumentation of other IT systems. Since the wiki is to be used mainly by technical staff, I just needed a way to make a quick intro to the wiki, without too much efford.
So, I made a quick tutorial for the Screwturn wiki that shows a few pages that explains about the various elements on the wiki page and the global functions. Like, where is the navigation menu, how to create a new page, how to edit a section of a page, what are categories etc.
Read my
page on the subject where I explain in detail how I did it.
