+Welcome, Copilot! This file provides context and coding guidelines for assisting with this React Native project. Instructions are divided
+into two sections: General Instructions and Project-Specific Instructions. General Instructions are shared across all projects within the
+RN team and include best practices applicable across projects. These should be updated via PRs to RN project template.
+
+When thinking of solutions, combine general instructions and project-specific instructions. However, project-specific instructions take
+precedence and can override general instructions. Project-specific instructions are tailored to the specific needs of the project and are
+updated throughout the development process.
+
+# ------------------------ GENERAL INSTRUCTIONS ------------------------
+
+### About
+
+- This is a React Native app built with Expo and TypeScript.
+- The project uses pnpm as its package manager.
+
+### Code Quality Tools
+
+- The project uses ESLint and Prettier for auto-formatting and enforcing coding rules.
+- Write unit tests using `jest` and `@testing-library/react-native`.
+- Write E2E tests using Maestro.
+
+### Code Style
+
+- Prefer destructuring for props and objects.
+- Use modern TypeScript syntax and features.
+- Use arrow functions for components.
+- Avoid deprecated or legacy APIs.
+- Use `async/await` for asynchronous operations.
+
+### Preferred Modules and Libraries
+
+- Use `expo-router` for navigation.
+- Prefer the usage of Expo libraries when available.
+
+### Chat and Communication
+
+- When suggesting code changes in chat, ensure imports are included at the top of the file.
+
+### Animations
+
+- Use react-native-reanimated and Skia for animations and drawing.
+- Avoid thread jumping in animations to ensure smooth performance. This means, try to access .value of sharedValue in worklets, not on JS thread.
+
+### Avoid
+
+- Avoid using `any` types. Always use specific types or interfaces.
+- Avoid nesting ternary expressions.
