-Lets run through how to create Netlify functions and connect them to our frontend application.

-1. Create React app

-3. Create a function
-4. Connect the function to the frontend app
+This application is using [React](https://reactjs.org/) for the frontend, [Netlify Functions](https://www.netlify.com/docs/functions/) for API calls, and [FaunaDB](https://fauna.com/) as the backing database.
