Nixpkgs is a collection of packages for the [Nix](https://nixos.org/nix/) package
manager. It is periodically built 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-17.03` for the latest
release and `nixos-unstable` for the latest successful build of master:

```
% git remote update channels
% git rebase channels/nixos-17.03
```

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

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