The "Yelp:" Project is a project that aims to upload the entire Help documentation for GNOME (known as Yelp) to the Furbuntu Wiki and let the community rewrite articles (either in part or in whole) for Furbuntu.
Any and all Yelp articles that are uploaded are designated with a Yelp:, thus why the project is called "Yelp:".
And because all the documentation of Yelp is under Wikipedia:GNU Free Documentation License v1.1 or higher, all of this is possible.
