15 [Nixpkgs](https://github.com/nixos/nixpkgs) is a collection of over
16 80,000 software packages that can be installed with the
17 [Nix](https://nixos.org/nix/) package manager. It also implements
18 [NixOS](https://nixos.org/nixos/), a purely-functional Linux distribution.

48 # Continuous Integration and Distribution
50 Nixpkgs and NixOS are built and tested by our continuous integration
51 system, [Hydra](https://hydra.nixos.org/).
53 * [Continuous package builds for unstable/master](https://hydra.nixos.org/jobset/nixos/trunk-combined)
54 * [Continuous package builds for the NixOS 22.05 release](https://hydra.nixos.org/jobset/nixos/release-22.05)
55 * [Tests for unstable/master](https://hydra.nixos.org/job/nixos/trunk-combined/tested#tabs-constituents)
56 * [Tests for the NixOS 22.05 release](https://hydra.nixos.org/job/nixos/release-22.05/tested#tabs-constituents)
58 Artifacts successfully built with Hydra are published to cache at
59 https://cache.nixos.org/. When successful build and test criteria are
60 met, the Nixpkgs expressions are distributed via [Nix
61 channels](https://nixos.org/manual/nix/stable/package-management/channels.html).
65 Nixpkgs is among the most active projects on GitHub. While thousands
66 of open issues and pull requests might seem a lot at first, it helps
67 consider it in the context of the scope of the project. Nixpkgs
68 describes how to build tens of thousands of pieces of software and implements a
69 Linux distribution. The [GitHub Insights](https://github.com/NixOS/nixpkgs/pulse)
70 page gives a sense of the project activity.
72 Community contributions are always welcome through GitHub Issues and
73 Pull Requests. When pull requests are made, our tooling automation bot,
74 [OfBorg](https://github.com/NixOS/ofborg) will perform various checks
75 to help ensure expression quality.
77 The *Nixpkgs maintainers* are people who have assigned themselves to
78 maintain specific individual packages. We encourage people who care
79 about a package to assign themselves as a maintainer. When a pull
80 request is made against a package, OfBorg will notify the appropriate
81 maintainer(s). The *Nixpkgs committers* are people who have been given
84 Most contributions are based on and merged into these branches:
86 * `master` is the main branch where all small contributions go
87 * `staging` is branched from master, changes that have a big impact on
88 Hydra builds go to this branch
89 * `staging-next` is branched from staging and only fixes to stabilize
90 and security fixes with a big impact on Hydra builds should be
91 contributed to this branch. This branch is merged into master when
92 deemed of sufficiently high quality

99 The infrastructure for NixOS and related projects is maintained by a
100 nonprofit organization, the [NixOS
101 Foundation](https://nixos.org/nixos/foundation.html). To ensure the
102 continuity and expansion of the NixOS infrastructure, we are looking
103 for donations to our organization.
105 You can donate to the NixOS foundation through [SEPA bank
106 transfers](https://nixos.org/donate.html) or by using Open Collective:
