+  I use Nix and Home Manager to manage my dotfiles and configure the programs I use, and it works on NixOS and standalone.
+---
+
+[As well as Nix managing packages][0] and [NixOS as your operating system][1], you can use Nix to manage your user configuration and dotfiles.
+
+Enter, Home Manager.
+
+Home Manager is available as a module for NixOS and a standalone package for other Linux distributions and macOS.
+
+With it, you can install and configure programs for specific users and create and manage dotfiles such as .gitconfig, .tmux.conf and .zshrc instead of using a tool like Stow.
+
+There's also the extra benefit that [you can write these files in the Nix language][2] and only focus on one configuration language.
+
+Nix and Home Manager will create the desired output file in whatever the program wants, whether it's JSON, ini, YAML or something else.
+
+A good example is [my .gitconfig configuration][3]. It includes settings for Git itself, aliases, global excludes, adds extra packages such as [git-instafix][4] and some environment variables.
+
+All in one file and all in one language.
