+
+## 📝 CODING STANDARDS
+
+### General Guidelines
+- **Consistency**: Follow existing code style
+- **Clarity**: Write clear, readable code
+- **Comments**: Add comments for complex logic
+- **Testing**: Write tests for new functionality
+- **Documentation**: Update relevant documentation
+
+### Flutter/Dart Standards
+
+#### Code Style
+```dart
+// Use meaningful variable names
+final List<LearningConcept> concepts = [];
+
+// Use const for compile-time constants
+const int maxRetries = 3;
+
+// Use proper naming conventions
+class LearningAnalytics {
+  Future<void> trackProgress() async {
+    // Implementation
+  }
+}
+
+// Use async/await for asynchronous operations
+Future<void> loadData() async {
+  final data = await apiService.getData();
+  processData(data);
+}
+```
+
+#### Widget Structure
+```dart
+class CustomWidget extends StatelessWidget {
+  final String title;
+  final VoidCallback? onTap;
+  
+  const CustomWidget({
+    required this.title,
+    this.onTap,
+    Key? key,
+  }) : super(key: key);
+
+  @override
+  Widget build(BuildContext context) {
+    return Container(
+      child: Text(title),
+    );
+  }
+}
+```
+
+#### State Management
+```dart
+// Use Riverpod providers
+final learningStateProvider = StateNotifierProvider<LearningStateNotifier, LearningState>(
+  (ref) => LearningStateNotifier(),
+);
+
+// Use proper provider naming
+final authProvider = Provider<AuthService>((ref) => AuthService());
+```
+
+### TypeScript/Node.js Standards
+
+#### Code Style
+```typescript
+// Use interfaces for type definitions
+interface User {
+  id: string;
+  email: string;
+  role: UserRole;
+}
+
+// Use proper error handling
+async function getUser(id: string): Promise<User> {
+  try {
+    const user = await userRepository.findById(id);
+    if (!user) {
+      throw new Error('User not found');
+    }
+    return user;
+  } catch (error) {
+    console.error('Error fetching user:', error);
+    throw error;
+  }
+}
+
+// Use proper function naming
+export class UserService {
+  async createUser(userData: CreateUserRequest): Promise<User> {
+    // Implementation
+  }
+}
+```
+
+### Python Standards
+
+#### Code Style
+```python
+# Use type hints
+from typing import List, Optional
+
+class VectorSearchService:
+    def __init__(self, dimension: int = 384) -> None:
+        self.dimension = dimension
+    
+    def search(self, query: np.ndarray, k: int = 10) -> List[Tuple[int, float]]:
+        """Search for similar vectors."""
+        # Implementation
+        pass
+
+# Use proper docstrings
+def process_text(text: str) -> ProcessedText:
+    """
+    Process text for embedding.
+    
+    Args:
+        text: The input text to process
+        
+    Returns:
+        ProcessedText: The processed text object
+    """
+    # Implementation
+    pass
+```

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
