 # ❄️ My NixOS Config
 
-```bash
-git clone https://github.com/Andrey0189/nixos-config
-mv nixos-config $HOME/nix # Config is supposed to be in the ~/nix directory
-cd $HOME/nix
-sudo nixos-rebuild switch --flake .
-home-manager switch --flake .
+This configuration is based on [&'s config](https://github.com/Andrey0189/nixos-config)
+
+## Users
+- [Sweetbread](./user/sweetbread)
+- [Chest](./user/chest)
+
+## Hosts
+- [Rias](./host/Rias)
+- [Senko](./host/Senko)
+- [Eclipse](./host/Eclipse)
+- [Impreza](./host/Impreza)
+
+## How does this work?
+The [flake](./flake.nix) file is the starting point. While installing/rebuilding
+the correct `host` is chosen, which includes `./host/${host}/configuration.nix`.
+
+It includes 2 (actually, more, but hey!) files:
+- [`./host/modules/common.nix`](./host/modules/common.nix): Common setting
+for all hosts (I don't say)
+- [`./user/common.nix`](./user/common.nix): Common settings for all users (you
+got the idea) and setup of [home-manager](https://github.com/nix-community/home-manager)
+
+It allows me to remove duplications and add multiple users to one host
+
+Example with Rias:
 ```
-Enjoy!
+./host/Rias/configuration.nix
+  ./host/Rias/modules/*
+  ./host/modules/gpu/nvidia.nix
+  ./host/modules/common.nix
+    ./host/Rias/hardware-configuration.nix
+    ./modules/host.nix
+      ./modules/host/*
+    ./host/modules/packages.nix
+  ./user/common.nix
+    ./user/sweetbread/home.nix
+      ./user/sweetbread/modules/*
+    ./modules/user.nix
+      ./modules/user/*
+```
+
+## Programs
+Most of programs are defined in [user modules](./modules/user)
