The official website of Debian GNU Linux Operating System. Debian is well known for its stability, security and freedom. The website is extensively well documented, with help and support options available to the new linux users at every step. I particularly liked their installation manual which is so detailed that it becomes boring at times.
Debian represents the freedom that Linux brings to the servers, the web and computers. It comes in many different flavors and Debian has many separate websites inside the main sites for packages, flavors, support and contributors. It also runs many mailing lists where users can subscribe and communitcate with other debian users.
