The '''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. 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 ''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.


None of the services are required to use Nix. None of these services are affiliated with the [[NixOS Foundation]].
<!--T:7-->
== Development of NixOS ==
Developers of ''NixOS'' mainly work on ''Nixpkgs'' to describe in text files in ''Nix'' language how software packages should be build. After peer review these changes are integrated in ''Nixpkgs''. Some of these packages are pre built on ''Hydra'' to reduce the update time for ''NixOS'' users.
