 ## Dev Container Setup (one time setup)
-1. Ensure you have Docker and X-11 forwarding installed on your device (google this)
-2. Clone the repo and edit devcontainer.json accordingly for your X-11 setup
+1. Ensure you have Docker and X-11 forwarding installed on your device. (google this)
+2. Clone the repo and edit devcontainer.json accordingly for your X-11 setup. If you're on an non-linux OS you can also just comment out the lines for mounting the X socket and uncomment the lines for the "desktop-lite" below. Then by going to `localhost:6080` and entering the password `vscode` you should be able to access a desktop environment through your browser if necessary. 
 3. In VSCode, first run `python3 setup_image.py` (alternatively run `echo "FROM t0mmyn/uavf_2024" > .devcontainer/Dockerfile` to download from a mirrored x86 image)
 4. Then open the command palette (cmd/ctrl+shift+p) and run `rebuild and reopen in dev container`
 5. To verify your setup, run `run_tests.sh`
