The forum is full of "Summary Posts" and explanations, and there are many different Google Docs.
It's so hard to follow it, and a lot of stuff is outdated or just wrong.
That's why we need a community wiki, where everyone can contribute.
I would prefer a simple wiki software (not MediaWiki), but also not as limited as github wiki.
Later when the API is final and the mod is working, we can add tutorials (setting up a server, making first plugin, ...),
and maybe a "Sponge Project History" page.
