Fedora is a Linux-based operating system that showcases the latest in free and open source software. Fedora is always free for anyone to use, modify, and distribute. It is built by people across the globe who work together as a community: the Fedora Project. The Fedora Project is open and anyone is welcome to join. The Fedora Project is out front for you, leading the advancement of free, open software and content.
The operating system is Fedora. It comes out twice a year or so. It's completely free, and we're committed to keeping it that way. It's the best combination of robust and latest software that exists in the free software world. The mindset is doing the right thing. To us, that means providing free and open software and content, at no cost, freely usable, modifiable, redistributable, and unencumbered by software patents.

The Fedora Project is a Red Hat sponsored and community supported open source project. Its goal is the rapid progress of free and open source software and content. The Fedora Project makes use of public forums, open processes, rapid innovation, meritocracy, and transparency in pursuit of the best operating system and platform that free and open source software can provide.
