7Nixpkgs is a collection of packages for the [Nix](https://nixos.org/nix/) package
8manager. It is periodically built and tested by the [hydra](http://hydra.nixos.org/)
9build daemon as so-called channels. To get channel information via git, add
10[nixpkgs-channels](https://github.com/NixOS/nixpkgs-channels.git) as a remote:
11
12```
13% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
14```
15
16For stability and maximum binary package support, it is recommended to maintain
17custom changes on top of one of the channels, e.g. `nixos-14.12` for the latest
18release and `nixos-unstable` for the latest successful build of master:
19
20```
21% git remote update channels
22% git rebase channels/nixos-14.12
23```
24
25For pull-requests, please rebase onto nixpkgs `master`.
26
27[NixOS](https://nixos.org/nixos/) linux distribution source code is located inside
28`nixos/` folder.
