I will create a document in each Github repository (project) that outlines in detail how to work with the tool. Though Github has some technical aspects, they are not that hard to grasp and you can get familiar with it really fast. The documentation format is the same as used in this forum, so it will help you write posts here too (without using the toolbar). There are easy (WYSIWYG, what you see is what you get, UI-based) editing and more handy (but slightly more technical) ways to contribute. I have been spending quite a bit of time already… go out for a walk now, but the guidelines will hopefully be ready this weekend.
