-# NixOS configuration
+# Sakamoto NixOS 
+Sakamoto NixOS is built with various profiles intended for reproducibility.
+
+## Installation
+As of now, it is still under construction. Thus, you can only access `desktop` profile for both `nixosConfiguration` and `homeConfiguration`. Follow the instructions below.
+
+1. Edit `info.nix` variables. There are various options such as the vpn section that you may need to modify. Otherwise, the program may not work.
+2. On the current directory, execute the following command:
+```
+$ nixos-rebuild switch --flake ./#desktop
+$ home-manager switch --flake ./#desktop
+```
