To be fair the whole FAQ would need some work. I'm always surprised people spent days or months putting together this kind of project, but wouldn't take an hour or two for proper copywriting. The project being open source, I'm sure they could even find someone to do it for free.

Documentation is difficult, and most people hate doing it. There's a lack of people who want to do documentation in opensourceland, and when someone does want to do docs, they also have to really understand the product, or have a senior dev work with them. Copywriting is easy for people who can write copy, but it's difficult for most people.
