+# Nix Dotfiles
+
+This is my folder where I migrate my current dotfile setup to [Nix](https://nixos.org/), [nix-darwin](https://github.com/LnL7/nix-darwin), and [home-manager](https://github.com/nix-community/home-manager).
+
+> [!DANGER] Warning
+> This is a work in progress and I am still learning Nix, so expect things to be broken.
+
+```sh
+# First time install
+nix run nix-darwin -- switch --flake ~/.config/nix-darwin
+```
+
+Make sure this is added to your path:
+
+```sh
+export PATH="/run/current-system/sw/bin:$PATH"
+```
+
+```sh
+# Switch to new configuration
+darwin-rebuild switch --flake ~/.dotfiles/nix
+```
