This is a new [**React Native**](https://reactnative.dev) project, bootstrapped using [`@react-native-community/cli`](https://github.com/react-native-community/cli). # Getting Started > **Note**: Make sure you have completed the [Set Up Your Environment](https://reactnative.dev/docs/set-up-your-environment) guide before proceeding. ## Step 1: Install Dependencies First, install the required dependencies: ```sh # Using npm npm install # OR using Yarn yarn install ``` ## Step 2: Start Metro You will need to run **Metro**, the JavaScript build tool for React Native. To start the Metro dev server, run the following command from the root of your React Native project: ```sh # Using npm npm start # OR using Yarn yarn start ``` ## Step 3: Build and run your app With Metro running, open a new terminal window/pane from the root of your React Native project, and use the following command to build and run your Android app: ### Android ```sh # Using npm npm run android # OR using Yarn yarn android ``` > **Note**: This project is configured for Android development only. If everything is set up correctly, you should see your new app running in the Android Emulator or your connected Android device. You can also build it directly from Android Studio. ## Step 4: Modify your app Now that you have successfully run the app, let's make changes! Open `App.tsx` in your text editor of choice and make some changes. When you save, your app will automatically update and reflect these changes — this is powered by [Fast Refresh](https://reactnative.dev/docs/fast-refresh). When you want to forcefully reload, for example to reset the state of your app, you can perform a full reload: - **Android**: Press the R key twice or select **"Reload"** from the **Dev Menu**, accessed via Ctrl + M (Windows/Linux) or Cmd ⌘ + M (macOS). ## Congratulations! :tada: You've successfully run and modified your React Native App. :partying_face: ### Now what? - If you're curious to learn more about React Native, check out the [docs](https://reactnative.dev/docs/getting-started). # Troubleshooting If you're having issues getting the above steps to work, see the [Troubleshooting](https://reactnative.dev/docs/troubleshooting) page. # Learn More To learn more about React Native, take a look at the following resources: - [React Native Website](https://reactnative.dev) - learn more about React Native. - [Getting Started](https://reactnative.dev/docs/environment-setup) - an **overview** of React Native and how setup your environment. - [Learn the Basics](https://reactnative.dev/docs/getting-started) - a **guided tour** of the React Native **basics**. - [Blog](https://reactnative.dev/blog) - read the latest official React Native **Blog** posts. - [`@facebook/react-native`](https://github.com/facebook/react-native) - the Open Source; GitHub **repository** for React Native.
