It recommends using Node 20 or later, cloning the repository, enabling the core pack, installing with pnpm, and starting the server so the demo runs at localhost. The demo updates pricing and other details when switching countries like the UK, Germany, Canada, and Australia, and it can generate a demo order when you pay. It also covers using staging or developer credentials by creating an env file with the test secret key and publishable key and placing the demo model into the API.
