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. | 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.

Users install the ''NixOS'' distribution on their computers just as any other Linux distribution. They read about packages to install and configuration options in ''Nixpkgs'' 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. | Users install the ''NixOS'' distribution on their computers just as any other Linux distribution.

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. | Developers of ''NixOS'' mainly work on ''Nixpkgs''.
