# nix-config

This repo stores nix configuration to manage my hosts running [NixOS](https://nixos.org/) and macOS.

The configuration is very specific to my own machines and setup, but it may be a useful reference for anyone else learning or experimenting with nix, whether it be on a personal workstation or a server environment.

## Prerequisites
