NixOS Foundation

Declarative builds and deployments

Our role is to support the infrastructure and development of the NixOS project as a whole. Most of the development is happening here: https://github.com/nixos/nix - the Nix cli and language reference implementation https://github.com/nixos/nixpkgs - package definitions for the Nix package manager and NixOS source code A few key points are: - keeping our ci up and running - hosting a trustworthy binary cache for the public - providing documentation for everything Nix - unblocking contributors and keeping things civil
