 ## 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. 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.
