 ## Layout
 
 - Everything under `./modules` gets auto-imported by `import-tree`
-- 
+
+| Directory     | Description |
+| ------------- | ----------- |
+| `hosts`       | Provides either `homeConfigurations` or `nixosConfigurations` |
+| `nix-tools`   | Nix-specific tools, like factory functions for use in the flakes |
+| `nixos`       | `flake.modules.nixos` |
+| `programs`    | flakes that provide `flake.modules` attributes for specific programs |
+| `services`    | flakes that provide configuration for running services |
+| `users`       | flakes that provide configuration for individual users with the `flake.factory.user` factory |
