Here are the links for the tutorials if you don't have them already:
Clone this repo to your computer and run npm install in both the root directory and inside the client folder.
You'll also need to add your own API keys + File IDs to server.js in the root.
After you have done that you'll need to run npm start in both the root and the client folder to start the two servers.
If you spot any mistakes with the repo OR the tutorials, let me know with an issue here or a response to the tutorials.
