+# NixOS configuration
+
+## Getting Started 
+
+### System rebuild
+1. (Optional) On ./system/users.nix, replace `biscuit` on `users.users.biscuit` with your own username. If you are creating a new user (by replacing `biscuit`), or ignoring the file, the default password is `very-insecure-password`. Make sure to replace it!
+2. Replace `hardware-configuration.conf`(each located at `nixos` folder) with your own. You can generate a config via `nixos-generate-config --dir ./nixos/`.
+3. While in this folder, rebuild your system using this command: `sudo nixos-rebuild switch --flake ./#${YOUR_CHOICE}`. For example, if you chose `biscuit` config, you type the following: `sudo nixos-rebuild switch --flake ./#biscuit`.
+
+### Home rebuild
