# Set up a React Application Locally

Hello and welcome!

Before starting this course, we recommend completing the [Introduction to GitHub Learning Lab](https://lab.github.com/githubtraining/introduction-to-github) first with the option for working locally in the command line.

### What's in our React App

Let's take a look of what our React App looks like right now. We will go through our file structure which is a [standard React setup](https://facebook.github.io/create-react-app/docs/getting-started). You will not be editing any files in this step, but the structure is important for future code references.


##### `package.json`

The `package.json` file is our roadmap of the app. It tells us the name of the app, the version, the different dependencies we need to run our app, and more.

##### `public/`

The `public/` directory contains our `index.html` file. The `index.html` file directs us to the rest of the web application that requires additional processing.

##### `src`

This is where most of your code will go. You'll notice we have `App.jsx` along with other `jsx` files. But, what is `jsx`? Think of `jsx` as a mix between `html` and `javascript`. We can write tags, functions, and classes. Take a look at the `App.jsx` file. Some of that contents might look familiar from `html`, like `

Questa issue è più una lezione di configurazione che una richiesta di modifica definita. Inizia con package.json, public/index.html e src/App.jsx, quindi segui i passaggi elencati per clonare, eseguire il checkout del branch, eseguire npm install e npm start; il completamento consiste nel raggiungere il registro dei voti essenziale all’indirizzo http://localhost:3000/.
