Parts of this document have been derived from the [Debian Social Contract](https://www.debian.org/social_contract). Comments are welcome. Please send them to our [gentoo-project@lists.gentoo.org](mailto:gentoo-project@lists.gentoo.org) mailing list. ## What is Gentoo? Gentoo in itself is a collection of free knowledge. Knowledge in this context can be defined as documentation and metadata concerned with concepts or domains relevant to operating systems and their components, as well as [free software](https://www.fsf.org/philosophy/free-sw.html) contributed by various developers to the Gentoo Project. Gentoo, the operating system, is derived from the base concept of knowledge described above. A Gentoo operating system should satisfy the self-hosting requirement. In other words, the operating system should be able to build itself from scratch using the aforementioned tools and metadata. If a product associated with an official Gentoo project does not satisfy these requirements, the product does not qualify as a Gentoo operating system. An official list of Gentoo projects is listed under the Gentoo Metastructure. A Gentoo project does not need to produce a Gentoo operating system in order to be officially recognized. ## Gentoo is and will remain free software We will release our contributions to Gentoo as free software, metadata or documentation, under the GNU General Public License version 2 (or later, at our discretion) or the Creative Commons - Attribution / Share Alike version 2 (or later, at our discretion). Any external contributions to Gentoo (in the form of freely-distributable sources, binaries, metadata or documentation) may be incorporated into Gentoo provided that we are legally entitled to do so. However, Gentoo will never depend upon a piece of software or metadata unless it conforms to the GNU General Public License, the GNU Lesser General Public License, the Creative Commons - Attribution/Share Alike or some other license approved by the Open Source Initiative ([OSI](https://www.opensource.org/licenses)).
