From Fedora Project Wiki
This stuff is totally a work in progress and you should help make it better. Thanks!
To send to Creative Commons and press peeps
The Fedora Project, a global community leading the advancement of free, open software and content, today finalized the conversion of its documentation and wiki to the Creative Commons Attribution-Share Alike 3.0 United States License, also known as the CC BY-SA. This content was changed from the Open Publication License (OPL). Every six months, the Fedora Project produces a Linux distribution, as well as supporting documentation for each release. Moving to the CC BY-SA allows for wider reach of this documentation as more people understand that they can share it in the same ways they can share the software included in Fedora.
