FreeBSD Documentation Project: Who are we?
The project is a fairly loosely knit group of people, and the only thing we have got in common is that we are subscribed to the mailing list FreeBSD-doc@FreeBSD.org.
Some of us can commit changes directly to the FreeBSD documentation tree. You can view a complete list of all FreeBSD developers with commit privileges, as well as a list of the principal committers for the FreeBSD Documentation Project.
Others do not have commit privileges, but they write and submit documentation nonetheless. Once the documentation has been submitted according to the Submit Documentation page, one of the committers will then review it and include it in the documentation set.
If you want to help out with the documentation project (and I fervently hope you do) all you have to do is subscribe to the mailing list and participate. As soon as you have done that, you're a member of the project.
