# Installation
Nix can be installed in various ways:
1. As a package manager on macOS, Linux, or WSL.
2. As the system environment manager on NixOS, a Linux distribution that utilizes Nix for system management.
This book primarily focuses on the usage of NixOS and Flakes. Therefore, we will skip content that pertains solely to Nix.
The installation process of NixOS is straightforward, but we won't delve into the specifics here. For more information, please visit the official download site at <https://nixos.org/download.html>.
