Making a French version looks like it’s far from being a priority, so I translated the first pages I had already written in French about the WikiPendium projet.
The target is now to compile docs into it, write everything in English, and make it’s structure evolve. Translations may be available in the future, but the project has to become somehow popular first.
The perimeter is not yet well defined, but undocumented things should come first and then things that you may find into books but not online. Online stuff may just be pointed at in a first time.
