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.
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:
Debian Reference: a terse user guide, focussing on shell commands
Release Notes: usually published with Debian updates, aiming at users upgrading the distribution
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:
Manuals: Those guides resemble books, because they comprehensively describe major topics. A lot of manuals listed below 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.
HOWTOs: Like the name indicates, the HOWTO documents describe how to do a particular thing, i.e. they offer detailed and practical advice about the way to do something.
FAQs: We have compiled several documents answering frequently asked questions. Debian-related questions are answered in the Debian FAQ. Additionally, there is a separate FAQ about Debian CD/DVD images, answering all sorts of questions about installation media.
Other (shorter) Documents: Please also check the list of shorter instructions.
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.
The following documents include quicker, shorter instructions:
Manpages
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: https://manpages.debian.org/
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).
