First, go to Phaser.io and download the library. From there, know that you need a live server to make this work. You can get this as an add-on in Atom and Visual Studio Code. I won’t run correctly otherwise.

Don’t forget to get the assets from GitHub.
Assets for the walkthrough Put these directly in the assets folder.
