Debian documentation FOR newbies BY newbies (and not-so-newbies).
Debian GNU/Linux is a Free software replacement for operating systems like Windows and MacOS and their applications. 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.
Everyone who uses Debian GNU/Linux was a newbie once, even if they were not a beginner. Being a Debian user also means being part of the Debian and GNU/linux communities. If the community gives you help, giving help to others is a way of giving something back to the community. One way of helping others is to document your experience of successfully solving a problem. Debian NewbieDOC helps to make this easy because the Debian NewbieDOC website is is a wiki. Anyone can edit pages and create new ones.
