GNU documentation principles

We believe the reader should be free to copy, update, and
redistribute GNU documentation, just like GNU software.

Originally, all our documentation was released under a short copyleft license, or
under the GNU General Public
License (GPL). In 2001, the GNU Free Documentation License
(FDL) was created to address needs that were not met by licenses
originally designed for software. For more information on free
documentation, please see Richard
Stallman’s essay, “Free
Software and Free Manuals.” A Texinfo version of that essay is available
for inclusion in manuals.

Contribute

Please help us write more documentation! This is one of the most
important ways to contribute to the free software movement. For more
details on this and other ways to help, click here.

GNU Press: another way to contribute is to help us expand
bookstore availability of GNU Press books. For this or any
reason, you can contact GNU Press.
