NixOS4Noobs is a tutorial which teaches you how to use NixOS. However, this isn't like most tutorials which teaches you everything, it instead just tries to teach a few things which you're very likely to encounter.

Due to the large scale of NixOS and how it can be configured and set up, NixOS4Noobs will only focus on a configuration-based system. This is where your entire operating system is controlled using the configuration.nix file and nothing else.

This tutorial targets the following users:

• Users of a device which only they will access (not a device for multiple users)
• Users that want to control NixOS using just the configuration file
• Users that want everything installed system-wide

This tutorial is not for the following users:

• Those who use a device with a need for multiple users (e.g. a family)
• Users that want a clear separation between system-wide and local programs and services

Having a configuration based system has various advantages, namely:

• It's easy to configure - everything is in one location
• If something goes wrong, it's easy to pinpoint where the problem is (e.g. some dodgy installation)
• It's a reproducible setup (If you want to replicate a system on another device, just copy the configuration and it'll set it all up exactly as you want it to)
