 ## Development
 
 The recommended way to develop new features is to use the tool as if you were running the demo. For testing new API features, you can create a new HTML file in `demo/`. The server in `demo.js` runs a static server from `demo/` so it will be served at `localhost:8080/<new-file>.html` automatically.
