This skeleton contains two different applications -- a front end, or "client," created with "Create React App," and a back end, or "API," created with Express.

In order to make both of them work together, you'll need to run both, but you can run just one or the other to start. As you begin working on this project, you'll first focus on the client, so you can more or less ignore the API portion of the code for now.

In order to run the client, you'll run the following commands:

cd client/
npm i
npm start

You should then be able to visit localhost:3000 in your browser and see the client running. If you make changes in the App.js file, you should see them reflected.

In order to run the server, you'll run the following commands:

cd api/
npm i
npm start

You should then be able to visit localhost:9000 in your browser and see the server running.
