Creating a high-quality free operating system also includes writing technical manuals which describe the operation and use of programs. The Debian project is making every effort to provide all users with good documentation in an easily accessible form. This page contains a collection of links, leading to installation guides, HOWTOs, FAQs, release notes, our Wiki, and more.

Quick Start

If you are new to Debian we recommend you start with the following two guides:

Do have these at hand when you make your first Debian installation, it will probably answer many questions and help you work with your new Debian system.

Later, you might want to go through these documents:


Most of the documentation included in Debian was written for GNU/Linux in general, but there is also some documentation written specifically for Debian. Basically, the documents are sorted into these categories:

Many of the manuals listed here are available both online and in Debian packages; in fact, most of the manuals on the website are extracted from their respective Debian packages. Choose a manual below for its package name and/or links to the online versions.

Manuals specific to Debian

Other (shorter) Documents

The following documents include quicker, shorter instructions:

Traditionally, all Unix programs are documented with manpages, reference manuals made available through the man command. They usually aren't meant for beginners, but document all features and functions of a command. The complete repository of all manpages available in Debian is online:
info files
Many GNU software is documented through info files instead of manpages. These files include detailed information of the program itself, options and example usage. Info pages are available through the info command.
README files
README files are simple text files describing a single item, usually a package. You can find a lot of these files in the /usr/share/doc/ subdirectories on your Debian system. In addition to the README file, some of those directories include configuration examples. Please note that larger programs' documentation is typically provided in a separate package (same name as the original package, but ending in -doc).
