# Install and configure app

Follow the source instructions for **app**. Read the prerequisites and configuration steps before running an example.

## Get started

1. Install dependencies

   ```bash
   npm install
   ```

2. Start the app

   ```bash
    npx expo start
   ```

In the output, you'll find options to open the app in a

- [development build](https://docs.expo.dev/develop/development-builds/introduction/)
- [Android emulator](https://docs.expo.dev/workflow/android-studio-emulator/)
- [iOS simulator](https://docs.expo.dev/workflow/ios-simulator/)
- [Expo Go](https://expo.dev/go), a limited sandbox for trying out app development with Expo

You can start developing by editing the files inside the **app** directory. This project uses [file-based routing](https://docs.expo.dev/router/introduction).

## Check the installation

After setup, continue with the [first example](/docs/up-to-code-app/quick-start-guide). If a command fails, compare the runtime version, working directory, and required configuration with the original README before changing dependencies.
