8Nixpkgs is a collection of packages for the [Nix](https://nixos.org/nix/) package
9manager. It is periodically built and tested by the [hydra](http://hydra.nixos.org/)
10build daemon as so-called channels. To get channel information via git, add
11[nixpkgs-channels](https://github.com/NixOS/nixpkgs-channels.git) as a remote:
12
13```
14% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
15```
16
17For stability and maximum binary package support, it is recommended to maintain
18custom changes on top of one of the channels, e.g. `nixos-16.03` for the latest
19release and `nixos-unstable` for the latest successful build of master:
20
21```
22% git remote update channels
23% git rebase channels/nixos-16.03
24```
25
26For pull-requests, please rebase onto nixpkgs `master`.
27
28[NixOS](https://nixos.org/nixos/) linux distribution source code is located inside
29`nixos/` folder.
