Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian uses the Linux kernel (the core of an operating system), but most of the basic OS tools come from the GNU project; hence the name GNU/Linux. Debian GNU/Linux provides more than a pure OS: it comes with over 18733 packages, precompiled software bundled up in a nice format for easy installation on your machine.
The Free Software Foundation (FSF), established in 1985, is dedicated to promoting computer users' rights to use, study, copy, modify, and redistribute modified computer programs. The FSF promotes the development and use of free software, particularly the GNU operating system, used widely in its GNU/Linux variant.
Debian-Community.org is an effort to give something back to the community that has a great share in making Debian the universal OS that it is. Many people contribute to Debian: obviously the developers and package maintainers, but also translators and artists and everybody who files bugs or helps someone else on a mailing list. If you want to be part of the Debian community, but don't want to become a developer or maintainer, this is the place for you.
You don't have to be a Debian newbie, or newcomer, to get help from the NewbieDOC site, but the documentation there aims to provide help at a level that Debian newbies will find useful. The documents address topics that Debian newbies often need help with.
