 ### Windows
 
+#### Option 1
+
+Run the automated installer script in PowerShell:
+
+```sh
+Invoke-RestMethod https://raw.githubusercontent.com/rojo-rbx/rokit/main/scripts/install.ps1 | Invoke-Expression
+```
+
+#### Option 2
+
 Download and run<sup>\*</sup> `rokit.exe` from the [latest release][latest-release] page - this will automatically install Rokit.
 
 <sup>\* Make sure to run `rokit.exe` **directly**, by double-clicking it in the File Explorer, for automatic installation to be triggered. <br/> If you would like to install Rokit from a terminal or shell such as PowerShell / CMD, run `rokit.exe self-install` instead.
