+# React Native Game Engine Expo TypeScript Template
+
+This template is designed to jumpstart your game development with React Native using the react-native-game-engine library and TypeScript. It comes pre-configured with Expo Dev Client, allowing for a faster and more integrated development workflow.
+
+## Getting Started
+
+### Prerequisites
+
+- Node.js
+- Expo CLI
+- eas-cli (for building and submitting your app using EAS Build and EAS Submit)
+
+### Setup
+
+Clone the repository to get started:
+
+```sh
+git clone https://github.com/nightness/react-native-game-engine-expo-typescript-template
+cd react-native-game-engine-expo-typescript-template
+```
+
+Install the dependencies:
+
+```sh
+npm install
+```
+
+### Development Workflow
+
+Start the project using the Expo dev client:
+
+```sh
+npm run start
+```
+
+To run the game on a specific platform, use the corresponding script:
+
+```sh
+npm run android # for Android
+npm run ios # for iOS
+npm run web # for Web
+```
+
+### Building and Submitting
+
+The `eas.json` file is configured with profiles for local, development, preview, and production builds:
+
+- `build:adhoc`: Build a local adhoc app binary locally.
+- `build:dev`: Build a development client app binary locally.
+- `build:preview`: Increment the app version, build and upload the app to Expo's preview channel.
+- `build:production`: Increment the app version, build and upload the app to Expo's production channel.
+- `eas:preview`: Build and submit the app to the preview channel automatically.
+- `eas:production`: Build and submit the app to the production channel automatically.
+- `submit:preview`: Submit the app to the preview channel.
+- `submit:production`: Submit the app to the production channel.
+- `update`: Update your app on the fly without needing to resubmit to app stores.
+
+```sh
+npm run build:adhoc # Build for physical device testing
+npm run build:dev # Build for Expo development client
+npm run build:preview # Build for preview
+npm run eas:preview # Build and submit for preview
+npm run eas:production # Build and submit for production
+```
+
+### Continuous Updates
+
+With EAS Update, you can keep your app up to date without waiting for app store reviews:
+
+```sh
+npm run update:preview # Update the preview channel
+npm run update:production # Update the production channel
+```
+
+## Project Structure
+
+- `assets`: Contains static assets such as images and sounds.
+- `game`: Core game logic.
+  - `entities`: Game entity components (e.g., `Balloon.tsx`).
+  - `systems`: Game system logic (e.g., `GameLoop.ts`).
+- `types.ts`: TypeScript type definitions and interfaces.
+
+## Modifying the Template
+
+To modify the template and create your own game, follow these steps:
+
+1. **Design Your Game**: Plan out your game's mechanics, rules, and entities.
+
+2. **Create Game Entities**: Modify or create new TypeScript React components in the `game/entities` directory to represent your game's entities.
+
+3. **Implement Game Logic**: Write the game logic inside the `game/systems` directory. The `GameLoop.ts` file is where you will define how your game state updates with time.
+
+4. **Update Assets**: Add or replace assets in the `assets` folder as needed for your game.
+
+5. **Define Types**: If you create new entities or systems, update the `types.ts` file to define the TypeScript types that correspond to your game's components.
+
+6. **Integrate Entities and Systems**: Use the `GameEngine.tsx` component to integrate your entities and systems into the game loop.
+
+7. **Launch the Game**: Use the Expo CLI to run and test your game.
+
+8. **Build and Publish**: Once your game is complete and tested, follow the Expo documentation to build and publish your game to the iOS App Store and Google Play Store.
