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.


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.
