+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:
+
+### Now what?
+
+- If you want to add this new React Native code to an existing application, check out the [Integration guide](https://reactnative.dev/docs/integration-with-existing-apps).
+- 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.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
