+## Quick Start
+
+```sh
+npx create-react-app my-app
+cd my-app
+npm start
+```
+
+> If you've previously installed `create-react-app` globally via `npm install -g create-react-app`, we recommend you uninstall the package using `npm uninstall -g create-react-app` or `yarn global remove create-react-app` to ensure that `npx` always uses the latest version.
+
+_([npx](https://medium.com/@maybekatz/introducing-npx-an-npm-package-runner-55f7d4bd282b) comes with npm 5.2+ and higher, see [instructions for older npm versions](https://gist.github.com/gaearon/4064d3c23a77c74a3614c498a8bb1c5f))_
+
+Then open [http://localhost:3000/](http://localhost:3000/) to see your app.
+
+When you’re ready to deploy to production, create a minified bundle with `npm run build`.

+</p>
+
+### Get Started Immediately
+
+You **don’t** need to install or configure tools like webpack or Babel. They are preconfigured and hidden so that you can focus on the code.
+
+Create a project, and you’re good to go.
+
+## Creating an App
+
+**You’ll need to have Node >= 14 on your local development machine** (but it’s not required on the server). You can use [nvm](https://github.com/creationix/nvm#installation) (macOS/Linux) or [nvm-windows](https://github.com/coreybutler/nvm-windows#node-version-manager-nvm-for-windows) to switch Node versions between different projects.
+
+To create a new app, you may choose one of the following methods:
+
+### npx
+
+```sh
+npx create-react-app@latest my-app
+```
+
+_([npx](https://medium.com/@maybekatz/introducing-npx-an-npm-package-runner-55f7d4bd282b) comes with npm 5.2+ and higher, see [instructions for older npm versions](https://gist.github.com/gaearon/4064d3c23a77c74a3614c498a8bb1c5f))_
+
+### npm
+
+```sh
+npm init react-app my-app
+```
+
+_`npm init <initializer>` is available in npm 6+_
+
+### Yarn
+
+```sh
+yarn create react-app my-app
+```
+
+_`yarn create` is available in Yarn 0.25+_
+
+### Selecting a template
+
+You can now optionally start a new app from a template by appending `--template [template-name]` to the creation command.
+
+If you don't select a template, we'll create your project with our base template.
+
+Templates are always named in the format `cra-template-[template-name]`, however you only need to provide the `[template-name]` to the creation command.
+
+```sh
+npx create-react-app my-app --template [template-name]
+```
+
+> You can find a list of available templates by searching for ["cra-template-\*"](https://www.npmjs.com/search?q=cra-template-*) on npm.
+
+Our [Custom Templates](custom-templates.md) documentation describes how you can build your own template.
+
+#### Creating a TypeScript app
+
+You can start a new TypeScript app using templates. To use our provided TypeScript template, append `--template typescript` to the creation command.
+
+```sh
+npx create-react-app my-app --template typescript
+```
+
+If you already have a project and would like to add TypeScript, see our [Adding TypeScript](adding-typescript.md) documentation.
+
+### Selecting a package manager
+
+When you create a new app, the CLI will use [npm](https://docs.npmjs.com) or [Yarn](https://yarnpkg.com/) to install dependencies, depending on which tool you use to run `create-react-app`. For example:
+
+```sh
+# Run this to use npm
+npx create-react-app my-app
+# Or run this to use yarn
+yarn create react-app my-app
+```
+
+## Output
+
+Running any of these commands will create a directory called `my-app` inside the current folder. Inside that directory, it will generate the initial project structure and install the transitive dependencies:
+
+```
+my-app
+├── README.md
+├── node_modules
+├── package.json
+├── .gitignore
+├── public
+│   ├── favicon.ico
+│   ├── index.html
+│   ├── logo192.png
+│   ├── logo512.png
+│   ├── manifest.json
+│   └── robots.txt
+└── src
+    ├── App.css
+    ├── App.js
+    ├── App.test.js
+    ├── index.css
+    ├── index.js
+    ├── logo.svg
+    ├── serviceWorker.js
+    └── setupTests.js
+```
+
+No configuration or complicated folder structures, only the files you need to build your app. Once the installation is done, you can open your project folder:
+
+```sh
+cd my-app
+```
+
+## Scripts
+
+Inside the newly created project, you can run some built-in commands:
+
+### `npm start` or `yarn start`
+
+Runs the app in development mode. Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
+
+The page will automatically reload if you make changes to the code. You will see the build errors and lint warnings in the console.

+</p>
+
+### `npm test` or `yarn test`
+
+Runs the test watcher in an interactive mode. By default, runs tests related to files changed since the last commit.
+
+[Read more about testing](running-tests.md).
+
+### `npm run build` or `yarn build`
+
+Builds the app for production to the `build` folder. It correctly bundles React in production mode and optimizes the build for the best performance.
+
+The build is minified and the filenames include the hashes.
+
+Your app is ready to be deployed.
