+A ready-to-run NixOS configuration with opinionated defaults.
+
+The goal of this config is to make it as easy as possible to build a NixOS system for an out-of-the-box experience similar to user-friendly distributions like Ubuntu, Fedora, or Mint. Options are available under the `aux.system` top-level namespace. Where possible, we provided simple boolean (true/false) flags for enabling things like GPU drivers and desktop environments. You can, of course, extend this template however you'd like.
 
 ## Getting Started
 
 1. Install a fresh copy of NixOS and boot into your new system.
 2. Download, copy, or clone this repository onto your new system.
-3. Run `nixos-generate-config --show-hardware-config` to generate your system's `hardware-configuration.nix` file. Copy this file into the `host` folder, overwriting the existing file.
+3. Run `nixos-generate-config --show-hardware-config` to generate your system's `hardware-configuration.nix` file. Copy this file into the `host` folder, overwriting the existing `hardware-configuration.nix` file.
 4. Edit `flake.nix` and set the following variables:
     1. Change `hostName` to the hostname you want to give this system.
     2. If your system is running on an architecture other than 64-bit Linux, change `platform` to the architecture that you're using. Details on the various options are documented in `flake.nix`.

+#### Nvidia GPU support
+
+For users with a hybrid Nvidia GPU setup (e.g. laptop users), there's some additional setup you need to do. This setup requires you to find the PCI bus IDs for your Nvidia GPU and your secondary GPU (usually an integrated Intel or AMD GPU). [The NixOS wiki has instructions on how to find these](https://nixos.wiki/wiki/Nvidia#Laptop_Configuration:_Hybrid_Graphics_.28Nvidia_Optimus_PRIME.29). Once you have the bus IDs, you can set `aux.system.gpu.nvidia.hybrid.busIDs.intel` or `aux.system.gpu.nvidia.hybrid.busIDs.amd`.
+
 ### Secure Boot support
 
 This configuration supports [Secure Boot](https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface/Secure_Boot) systems, but with some additional setup required. Secure Boot is a UEFI standard meant to prevent the pre-boot process by requiring boot images to be signed by a trusted authority. The goal is to prevent tampering, e.g. by a malicious third-party replacing your kernel image with a compromised image. In NixOS, Secure Boot support is provided by the [Lanzaboote](https://github.com/nix-community/lanzaboote) project.
