== Overview ==

'''Debian''' is a [[Free software|free]] and [[Open-source software|open-source]] [[Linux distribution]] developed by the Debian Project. It is one of the oldest and most influential Linux distributions, first announced in 1993 by [[Ian Murdock]]. Debian is known for its strict adherence to the [[Debian Free Software Guidelines]], its robust package management system based on [[dpkg]] and [[APT]], and its commitment to stability and security. The project is governed by the [[Debian Social Contract]] and is maintained by a large community of volunteer developers.

== History ==

Debian was founded in August 1993 by Ian Murdock, who named it after himself and his then‑girlfriend Debra Lynn. The initial release, Debian 0.01, was completed in September 1993. The project quickly gained momentum and became a base for many other distributions, most notably [[Ubuntu]], which was first released in 2004 and is derived from Debian's unstable branch. The Debian Project pioneered the concept of a community‑governed, non‑commercial Linux distribution, and its development model has been widely emulated.

== Features ==

Debian is renowned for its vast software repository, containing over 59,000 packages as of its latest stable release. It supports multiple [[computer architecture]]s, including x86, AMD64, ARM, MIPS, and PowerPC. The distribution uses the [[dpkg]] package management tool and the [[APT]] (Advanced Package Tool) for package installation, removal, and updates. Debian offers three main branches: '''Stable''' (for production use), '''Testing''' (for more recent software with acceptable stability), and '''Unstable''' (also known as ''Sid'', where active development occurs). Releases are named after characters from the animated film ''Toy Story''; for example, Debian 12 is ''Bookworm'' and Debian 11 is ''Bullseye''.

The Debian Project also maintains the [[Debian Social Contract]] and the [[Debian Free Software Guidelines]], which define the project's commitment to free software. These guidelines have been adopted by the [[Open Source Initiative]] as the basis for the [[Open Source Definition]].
