+## Install NixOS-WSL in Windows
+
+If you're interested in running nixified.ai in the Windows Subsystem for Linux, you'll need to enable the WSL and then install NixOS-WSL via it. We provide a script that will do everything for you.
+
+1. Execute the following in Powershell
+
+   `Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/nixified-ai/flake/install.ps1'))`
+
+The WSL must be installed via the Windows Store. The script will make an attempt to enable it automatically, but this only works on a fresh system, not one that has been modified manually.
+
+See the following documentation from Microsoft for the details on how to enable and use the WSL manually
