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. 29 30* [NixOS installation instructions](https://nixos.org/nixos/manual/#ch-installation) 31* [Documentation (Nix Expression Language chapter)](https://nixos.org/nix/manual/#ch-expression-language) 32* [Manual (How to write packages for Nix)](https://nixos.org/nixpkgs/manual/) 33* [Manual (NixOS)](https://nixos.org/nixos/manual/) 34* [Continuous package builds for unstable/master](https://hydra.nixos.org/jobset/nixos/trunk-combined) 35* [Continuous package builds for 14.12 release](https://hydra.nixos.org/jobset/nixos/release-14.12) 36* [Tests for unstable/master](https://hydra.nixos.org/job/nixos/trunk-combined/tested#tabs-constituents) 37* [Tests for 14.12 release](https://hydra.nixos.org/job/nixos/release-14.12/tested#tabs-constituents) 38 39Communication: 40 41* [Mailing list](http://lists.science.uu.nl/mailman/listinfo/nix-dev) 42* [IRC - #nixos on freenode.net](irc://irc.freenode.net/#nixos)
