+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: Start Metro
+
+First, 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 2: Build and run your app
+
+With Metro running, open a new terminal window/pane from the root of your React Native project, and use one of the following commands to build and run your Android or iOS app:
+
+### Android
+
+```sh
+# Using npm
+npm run android
+
+# OR using Yarn
+yarn android
+```
+
+### iOS
+
+For iOS, remember to install CocoaPods dependencies (this only needs to be run on first clone or after updating native deps).
+
+The first time you create a new project, run the Ruby bundler to install CocoaPods itself:
+
+```sh
+bundle install
+```
+
+Then, and every time you update your native dependencies, run:
+
+```sh
+bundle exec pod install
+```
+
+For more information, please visit [CocoaPods Getting Started guide](https://guides.cocoapods.org/using/getting-started.html).
+
+```sh
+# Using npm
+npm run ios
+
+# OR using Yarn
+yarn ios
+```
+
+If everything is set up correctly, you should see your new app running in the Android Emulator, iOS Simulator, or your connected device.
+
+This is one way to run your app — you can also build it directly from Android Studio or Xcode.
+
+## Step 3: 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 <kbd>R</kbd> key twice or select **"Reload"** from the **Dev Menu**, accessed via <kbd>Ctrl</kbd> + <kbd>M</kbd> (Windows/Linux) or <kbd>Cmd ⌘</kbd> + <kbd>M</kbd> (macOS).
+- **iOS**: Press <kbd>R</kbd> in iOS Simulator.
+
+## Congratulations! :tada:
+
+You've successfully run and modified your React Native App. :partying_face:
