Nixpkgs is a collection of packages for the [Nix](https://nixos.org/nix/) package manager. It is periodically build and tested by the [hydra](http://hydra.nixos.org/) build daemon as so-called channels. To get channel information via git, add [nixpkgs-channels](https://github.com/NixOS/nixpkgs-channels.git) as a remote:

```
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
```

For stability and maximum binary package support, it is recommended to maintain custom changes on top of one of the channels, e.g. `nixos-14.12` for the latest release and `nixos-unstable` for the latest successfully build master:

```
% git remote update channels
% git rebase channels/nixos-14.12
```

For pull-requests, please rebase onto nixpkgs `master`.

[NixOS](https://nixos.org/nixos/) linux distribution source code is located inside `nixos/` folder.
