===Repositories===
The following official binary repositories exist:<ref>{{cite web |url=https://wiki.archlinux.org/index.php/Official_Repositories |title=Official Repositories |website=ArchWiki |access-date=23 November 2012 |archive-url=https://web.archive.org/web/20121118092608/https://wiki.archlinux.org/index.php/Official_Repositories |archive-date=18 November 2012 |url-status=live }}</ref>
*''core'', which contains all the packages needed to set up a base system. Packages in this repository include kernel packages and shell languages. 
*''extra'', which holds packages not required for the base system, including desktop environments and programs. 
*''multilib'', a centralized repository for x86-64 users to more readily support 32-bit applications in a 64-bit environment. Packages in this repository include [[Steam (service)|Steam]] and [[Wine (software)|Wine]]. 
Additionally, there are ''testing'' repositories which include binary package candidates for other repositories. Currently, the following testing repositories exist:
*''core-testing'', with packages for ''core''.
*''extra-testing'', with packages for ''extra''.
*''multilib-testing'', with packages for ''multilib''.
The ''core-staging'' and ''extra-staging'' repositories are used for some rebuilds to avoid broken packages in ''testing''. The developers recommend not using these repositories for any reason, stating that any system updating from them will "unquestionably break."<ref>{{Cite web|title=Official repositories - ArchWiki|url=https://wiki.archlinux.org/title/Official_repositories#Staging_repositories|access-date=2022-02-01|website=wiki.archlinux.org|archive-date=11 January 2023|archive-url=https://web.archive.org/web/20230111044308/https://wiki.archlinux.org/title/Official_repositories#Staging_repositories|url-status=live}}</ref>

There are also two other repositories that include the newest version of certain desktop environments.
*''gnome-unstable'', which contains packages of a new version of the software from [[GNOME]] before being released into ''testing''.
*''kde-unstable'', which contains packages of a new version of [[KDE]] software before being released into ''testing.''
The ''unstable'' repository was dropped in July 2008 and most of the packages moved to other repositories.<ref>{{cite web |url=https://www.archlinux.org/static/magazine/2008/newsletter-2008-Aug-04.html |title=Arch Linux Newsletter 08-04-2008 |website=Arch Linux |date=4 August 2008 |access-date=19 October 2009 |archive-url=https://web.archive.org/web/20130603175852/https://www.archlinux.org/static/magazine/2008/newsletter-2008-Aug-04.html |archive-date=3 June 2013}}</ref> The ''community'' repository was merged with ''extra'' in May 2023.<ref>{{Cite web |last=Larabel |first=Michael |date=2023-05-16 |title=Arch Linux Prepares For Repository Changes, Discontinuing SVN Access |url=https://www.phoronix.com/news/Arch-Linux-Discontinues-SVN |access-date=2023-05-24 |website=[[Phoronix]] |archive-date=24 May 2023 |archive-url=https://web.archive.org/web/20230524212743/https://www.phoronix.com/news/Arch-Linux-Discontinues-SVN |url-status=live }}</ref><ref>{{Cite web |last=van der Waa |first=Jelle |date=2023-05-15 |title=Git migration announcement |url=https://archlinux.org/news/git-migration-announcement/ |access-date=2023-05-24 |website=Arch Linux |archive-date=24 May 2023 |archive-url=https://web.archive.org/web/20230524175827/https://archlinux.org/news/git-migration-announcement/ |url-status=live }}</ref> In addition to the official repositories, there are a number of unofficial user repositories.

The most well-known unofficial repository is the [[#AUR|Arch User Repository]], or AUR, hosted on the Arch Linux site. The AUR does not host binary packages but instead a collection of build scripts known as [[#PKGBUILD|PKGBUILDs]]. PKGBUILD scripts are executed by the <code>makepkg</code> command, which downloads the necessary files from the software's repository and builds them using the Arch build system.

The Arch Linux repositories contain both [[Free and open-source software|libre]] and [[Proprietary software|nonfree]] software, and the default Arch Linux kernel contains [[Proprietary device driver|nonfree proprietary blobs]], hence the distribution is not endorsed by the GNU project.<ref>{{cite web |url=https://www.gnu.org/distros/common-distros.html#Arch |title=Explaining Why We Don't Endorse Other Systems |publisher=[[GNU Project]] |access-date=28 September 2011 |archive-url=https://web.archive.org/web/20110424061731/https://www.gnu.org/distros/common-distros.html#Arch |archive-date=24 April 2011 |url-status=live }}</ref> The linux-libre kernel can be installed from the AUR or by enabling [[Parabola GNU/Linux-libre|Parabola's]] repositories.
