Why isn't lot of information just inside the project repositories for open source projects? It is text thus space it takes is trivial. At least if images are not needed. It would be versioned so stay in relatively sync with versions of code at time. FAQ and basic configuration things for commonly asked questions could be easily be stored in documents. Why is this not being done? Wouldn't it be trivial amount of work?
