+
+---
+
+## 💿️ Installation
+
+> Your need to add your own device [flake.nix](./flake.nix), and create configuration in [system/dev](./system/dev/) (don't forget the `hardware-configuration.nix` generated with `nixos-generate-config`)
+
+### Example
+
+```
+system/dev/
+├── <your-device-name>
+    ├── boot.nix # You can add extra boot options here 
+    ├── default.nix # Import modules you need
+    └── hardware-configuration.nix # Your hardware configuration
+```
+
+`flake.nix`
+
+```nix
+nixosConfigurations = {
+  <your-device-name> = nixpkgs.lib.nixosSystem {
+    modules = [
+      nix-index-database.nixosModules.nix-index
+      ./system/dev/<your-device-name>
+    ];
+    specialArgs = {
+      inherit inputs system nix-version;
+    };
+  };
+};
+```
+
+### ❄️ Flake
+
+> home manager is configured to rebuild with NixOS
+
+OS Install
+
+```bash
+nixos-install --flake .#<your device name>
+```
+
+Rebuild Switch
+
+```bash
+nixos-rebuild switch --flake .#<your device name>
+```
