About the Free Software Foundation

The Free Software Foundation, founded in 1985, is dedicated to promoting computer users' right to use, study, copy, modify, and redistribute computer programs. The FSF promotes the development and use of free (as in freedom) software -- particularly the GNU operating system and its GNU/Linux variants -- and free documentation for free software. The FSF also helps to spread awareness of the ethical and political issues of freedom in the use of software, and its Web sites, located at fsf.org and gnu.org, are an important source of information about GNU/Linux. Donations to support the FSF's work can be made at http://donate.fsf.org. Its headquarters are in Boston, MA, USA.

About Free Software and Open Source

The free software movement's goal is freedom for computer users. Some, especially corporations, advocate a different viewpoint, known as "open source," which cites only practical goals such as making software powerful and reliable, focuses on development models, and avoids discussion of ethics and freedom. These two viewpoints are different at the deepest level. For more explanation, see http://www.gnu.org/philosophy/open-source-misses-the-point.html.

About the GNU Operating System and Linux

Richard Stallman announced in September 1983 the plan to develop a free software Unix-like operating system called GNU. GNU is the only operating system developed specifically for the sake of users' freedom. See http://www.gnu.org/gnu/the-gnu-project.html.

In 1992, the essential components of GNU were complete, except for one, the kernel. When in 1992 the kernel Linux was re-released under the GNU GPL, making it free software, the combination of GNU and Linux formed a complete free operating system, which made it possible for the first time to run a PC without non-free software. This combination is the GNU/Linux system. For more explanation, see http://www.gnu.org/gnu/gnu-linux-faq.html.
