+  If you like the declarative approach to installing and configuring packages with Nix, you do the same with your entire operating system with NixOS.
+---
+
+Yesterday, [I showed some of the Nix programming language][0] and how to use it to perform tasks such as installing and configuring packages.
+
+I like this declarative approach as you know everything installed on your system and its configuration.
+
+[There are no random or leftover packages or configuration files][1].
+
+The Nix package manager can be installed on Linux or macOS, but you can also use Nix to configure your whole operating system in a declarative way thanks to NixOS.
+
+As well as installing and configuring packages, you can define your firmware version, boot loader, disk partitioning, user accounts and more.
+
+I used to do this type of automation with Ansible but switched to NixOS soon after trying Nix on another Linux distribution.
+
+If I need to work on a different laptop, like when mine recently died, I can apply the same configuration and get all the same programs and configurations as before.
+
+If you want to see my current NixOS setup, you can [see it on my GitHub][2].
