Nix is a powerful package manager for Linux and other Unix systems that makes package management reliable and reproducible. Please refer to the Nix manual for more details.
On Linux and macOS the easiest way to install Nix is to run the following shell command (as a user other than root):
$ curl -L https://nixos.org/nix/install | sh
Information on additional installation methods is available on the Nix download page.
See our Hacking guide in our manual for instruction on how to build nix from source with nix-build or how to get a development environment.
Nix is released under the LGPL v2.1.
