	Developers of ''NixOS'' mainly work on ''Nixpkgs''. ''NixOS'' development itself is compromised of three large areas as well as some others which are smaller by volume (but no less important). The major ones include packaging, the module system, and documentation. Packaging is done in ''Nixpkgs'' and is not exclusive to ''NixOS'' or even Linux-based platforms. Maintainers of packages which are not exclusive to ''NixOS'' (such as tooling required to run the distribution itself) usually take care of multiple platforms although not strictly required. The module system is the way in which services running on ''NixOS'' are primarily configured. This area stretches from "low-level" configuration such as ''systemd'' unit files or providing custom kernel configuration up to configuration file generation for specific services. The module system is the primary way for users to configure ''NixOS'', and lives in the <code>nixos/</code> subdirector of ''Nixpkgs''. Documentation is largely embedded in packaging and module system data, although free-standing markdown files are also contained in the ''Nixpkgs'' repository. Documentation also includes maintaining the website, Wiki, and other aspects of the wider ecosystem. The first two categories are almost exclusively ''Nix'' language code written in text files, while the latter is a mix of ''Nix'' code, markdown files, and various other formats.

The '''Core Nix Ecosystem''' is a collection of technologies designed to reproducibly build and declaratively configure and manage packages and systems as well as their dependencies. It achieves this by translating the functional paradigm from the program to the system domain by utilizing a dynamic, functional and lazy DSL called the [[Overview of the Nix Language|Nix Language]] for specifying reproducible builds.

In addition there are many other [[applications]] ('''''Extended Nix Ecosystem)''''' developed by the Nix community, utilizing and supporting these core technologies.

== Usage of NixOS ==
Users install the ''NixOS'' distribution on their computers just as any other Linux distribution. They read about packages to install and configuration options in ''Nixpgs'' via https://search.nixos.org and this wiki. They use the ''Nix'' language to declaratively describe in a text file what software packages should be installed and how the system should be configured. They run 2 command line programs in a terminal to transform the system into the described system. They use the system as any other Linux system.
