In the project directory, run npm install to install required dependencies. The project has two dependencies - jquery for dom manipulation, and keymaster to make handling keyboard events more convenient
A basic web server for the project (because of cors issues), if you a node.js environment is available the quickest way would be to install http-server - a basic static server that you can run off the shelf without any config or code required. You can use it as follows:
npm i -g http-server
cd project_directory
http-server
Then browse to the port your server is running on (example http://localhost:8080)
