Nixpkgs is a collection of packages for the [Nix](https://nixos.org/nix/) package | ||
manager. It is periodically built and tested by the [Hydra](https://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: | ||
[Nixpkgs](https://github.com/nixos/nixpkgs) is a collection of over | ||
40,000 software packages that can be installed with the | ||
[Nix](https://nixos.org/nix/) package manager. It also implements | ||
[NixOS](https://nixos.org/nixos/), a purely-functional Linux distribution. | ||
|
||
``` | ||
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git | ||
``` | ||
# Manuals | ||
|
||
For stability and maximum binary package support, it is recommended to maintain | ||
custom changes on top of one of the channels, e.g. `nixos-19.03` for the latest | ||
release and `nixos-unstable` for the latest successful build of master: | ||
* [NixOS Manual](https://nixos.org/nixos/manual) - how to install, configure, and maintain a purely-functional Linux distribution | ||
* [Nixpkgs Manual](https://nixos.org/nixpkgs/manual/) - contributing to Nixpkgs and using programming-language-specific Nix expressions | ||
* [Nix Package Manager Manual](https://nixos.org/nix/manual) - how to write Nix expresssions (programs), and how to use Nix command line tools | ||
|
||
``` | ||
% git remote update channels | ||
% git rebase channels/nixos-19.03 | ||
``` | ||

# Other Project Repositories | ||
|
||
The sources of all offical Nix-related projects are in the [NixOS | ||
organization on GitHub](https://github.com/NixOS/). Here are some of | ||
the main ones: | ||
|
||
* [Nix](https://github.com/NixOS/nix) - the purely functional package manager | ||
* [NixOps](https://github.com/NixOS/nixops) - the tool to remotely deploy NixOS machines | ||
* [Nix RFCs](https://github.com/NixOS/rfcs) - the formal process for making substantial changes to the community | ||
* [NixOS homepage](https://github.com/NixOS/nixos-homepage) - the [NixOS.org](https://nixos.org) website | ||
* [hydra](https://github.com/NixOS/hydra) - our continuous integration system | ||
* [NixOS Artwork](https://github.com/NixOS/nixos-artwork) - NixOS artwork | ||
|
||
[NixOS](https://nixos.org/nixos/) Linux distribution source code is located inside | ||
`nixos/` folder. | ||
# Continuous Integration and Distribution | ||
|
||
Nixpkgs and NixOS are built and tested by our continuous integration | ||
system, [Hydra](https://hydra.nixos.org/). | ||

* [Documentation (Nix Expression Language chapter)](https://nixos.org/nix/manual/#ch-expression-language) | ||

* [Tests for unstable/master](https://hydra.nixos.org/job/nixos/trunk-combined/tested#tabs-constituents) | ||

||
Communication: | ||
Artifacts successfully built with Hydra are published to cache at | ||
https://cache.nixos.org/. When successful build and test criteria are | ||
met, the Nixpkgs expressions are distributed via [Nix | ||
channels](https://nixos.org/nix/manual/#sec-channels). The channels | ||
are provided via a read-only mirror of the Nixpkgs repository called | ||
[nixpkgs-channels](https://github.com/NixOS/nixpkgs-channels). | ||

# Contributing | ||
|
||
Nixpkgs is among the most active projects on GitHub. While thousands | ||
of open issues and pull requests might seem a lot at first, it helps | ||
consider it in the context of the scope of the project. Nixpkgs | ||
describes how to build over 40,000 pieces of software and implements a | ||
Linux distribution. The [GitHub Insights](https://github.com/NixOS/nixpkgs/pulse) | ||
page gives a sense of the project activity. | ||
|
||
Community contributions are always welcome through GitHub Issues and | ||
Pull Requests. When pull requests are made, our tooling automation bot, | ||
[OfBorg](https://github.com/NixOS/ofborg) will perform various checks | ||
to help ensure expression quality. | ||
|
||
The *Nixpkgs maintainers* are people who have assigned themselves to | ||
maintain specific individual packages. We encourage people who care | ||
about a package to assign themselves as a maintainer. When a pull | ||
request is made against a package, OfBorg will notify the appropriate | ||
maintainer(s). The *Nixpkgs committers* are people who have been given | ||
permission to merge. | ||
|
||
Most contributions are based on and merged into these branches: | ||
|
||
* `master` is the main branch where all small contributions go | ||
* `staging` is branched from master, changes that have a big impact on | ||
Hydra builds go to this branch | ||
* `staging-next` is branched from staging and only fixes to stabilize | ||
and security fixes with a big impact on Hydra builds should be | ||
contributed to this branch. This branch is merged into master when | ||
deemed of sufficiently high quality | ||
|
