+## Windows Setup
+___
+Devbox CLI is not supported on Windows, but you can still use it with VSCode by using Windows Subsystem for Linux ([WSL](https://learn.microsoft.com/en-us/windows/wsl/install)). If you've set up WSL, follow these steps to integrate your Devbox shell environment with VSCode:
 
+1. [Install](https://www.jetpack.io/devbox/docs/installing_devbox/) Devbox in WSL.
+2. Navigate to your project directory. (`C:\Users` is `/mnt/c/Users/` in WSL).
+3. Run `devbox init` if you don't have a devbox.json file.
+4. Run `devbox shell`
+5. Run `code .` to open VSCode in Windows and connect it remotely to your Devbox shell in WSL.
 ## Manual Setup
