 This holds my .nix files for NixOS
 
+Nix files: (nix-configs/)
+
+- `configuration.nix` : This is the main file for the base system including some applications that I use
+- `plasma.nix` : This file is for the desktop, login manager and other KDE applications
+- `programs.nix` : This file adds applications like Slack, Discord and virt-manager including turning on the services
+- `oryp6.nix` : This file is mainly for my System76 Oryx Pro (oryp6) to add and enable the NVIDIA driver from stable
+- `hp-omen.nix` : This file is mainly for my HP Omen to add and enable the NVIDIA driver from stable
+- `rpi4.nix` : This file is to configure a Raspberry Pi 4B
+- `unstable.nix` : This file has the applications that need to be from unstable to work like ProtonVPN software
