 1 | This project was bootstrapped with Create React App (CRA) v4 and then `babylonjs-react` was added.
 2 | For TypeScript
 3 | ```bash
 4 | npx create-react-app your-babylonjs-app --template typescript
 5 | ```
 6 | 
 7 | Add babylonjs dependencies:
 8 | ```bash
 9 | yarn add react-babylonjs
10 | yarn add @babylonjs/core
11 | yarn add @babylonjs/gui
12 | # loaders are optional
13 | yarn add @babylonjs/loaders
14 | ```
15 | 
16 | All of the code for the site is in `/src/App.tsx`
17 | 
18 | In the project directory, you can run:
19 | 
20 | ### `npm start` / `yarn start`
21 | 
22 | Runs the app in the development mode.<br>
23 | Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
24 | 
25 | The page will reload if you make edits.<br>
26 | You will also see any lint errors in the console.
