[[https://www.gnu.org/software/guix/][GNU Guix]] (IPA: /ɡiːks/) is a purely functional package manager, and
associated free software distribution, for the [[https://www.gnu.org/gnu/gnu.html][GNU system]]. In addition
to standard package management features, Guix supports transactional
upgrades and roll-backs, unprivileged package management, per-user
profiles, and garbage collection.
It provides [[https://www.gnu.org/software/guile/][Guile]] Scheme APIs, including a high-level embedded
domain-specific languages (EDSLs) to describe how packages are to be
built and composed.
GNU Guix can be used on top of an already-installed GNU/Linux distribution, or
it can be used standalone (we call that “Guix System”).
Guix is based on the [[https://nixos.org/nix/][Nix]] package manager.
* Requirements
If you are building Guix from source, please see the manual for build
instructions and requirements, either by running:
