+## Clean Architecture Overview
+
+**EN**: This template implements Clean Architecture (also known as Onion Architecture or Hexagonal Architecture) to achieve:
+- **Independence of Frameworks**: Business logic doesn't depend on frameworks
+- **Testability**: Business rules can be tested without UI, database, or external services
+- **Independence of UI**: UI can change without changing business rules
+- **Independence of Database**: Business rules are not bound to database
+- **Independence of External Services**: Business rules don't know about external services
+
+**VI**: Template này triển khai Clean Architecture (còn gọi là Onion Architecture hoặc Hexagonal Architecture) để đạt được:
+- **Độc lập với Frameworks**: Business logic không phụ thuộc vào frameworks
+- **Khả năng kiểm thử**: Business rules có thể được test mà không cần UI, database hoặc external services
+- **Độc lập với UI**: UI có thể thay đổi mà không ảnh hưởng business rules
+- **Độc lập với Database**: Business rules không bị ràng buộc với database
+- **Độc lập với External Services**: Business rules không biết về external services
+
+## Layer Responsibilities / Trách Nhiệm Các Lớp
+
+### 1. Domain Layer (Core) / Lớp Domain (Lõi)

+```
+
+**EN**: All dependencies point inward. The Domain layer has no dependencies on any other layer.
+
+**VI**: Tất cả dependencies đều hướng vào trong. Lớp Domain không phụ thuộc vào bất kỳ lớp nào khác.
+
+## Design Patterns / Mẫu Thiết Kế
+
+### Repository Pattern
+
+**EN**: Abstracts data access logic and provides a collection-like interface for accessing domain objects.
+
+**VI**: Trừu tượng hóa logic truy cập dữ liệu và cung cấp interface giống collection để truy cập domain objects.
+
+```csharp
+// Domain Layer - Interface
+public interface IUserRepository
+{
+    Task<User?> GetByIdAsync(Guid id);
+    Task<IEnumerable<User>> GetAllAsync();
+    Task AddAsync(User user);
+    Task UpdateAsync(User user);
+    Task DeleteAsync(Guid id);
+}
+
+// Infrastructure Layer - Implementation
+public class UserRepository : IUserRepository
+{
+    private readonly ApplicationDbContext _context;
+    
+    public UserRepository(ApplicationDbContext context)
+    {
+        _context = context;
+    }
+    
+    public async Task<User?> GetByIdAsync(Guid id)
+    {
+        return await _context.Users.FindAsync(id);
+    }
+    // ... other implementations
+}
+```
+
+### Service Pattern
+
+**EN**: Encapsulates business logic and orchestrates operations across repositories.
+
+**VI**: Đóng gói business logic và điều phối các operations giữa các repositories.
+
+```csharp
+// Application Layer
+public interface IUserService
+{
+    Task<UserDto> GetUserAsync(Guid id);
+    Task<UserDto> CreateUserAsync(CreateUserDto dto);
+}
+
+public class UserService : IUserService
+{
+    private readonly IUserRepository _userRepository;
+    private readonly IMapper _mapper;
+    
+    public UserService(IUserRepository userRepository, IMapper mapper)
+    {
+        _userRepository = userRepository;
+        _mapper = mapper;
+    }
+    
+    public async Task<UserDto> GetUserAsync(Guid id)
+    {
+        var user = await _userRepository.GetByIdAsync(id);
+        if (user == null) throw new NotFoundException("User not found");
+        
+        return _mapper.Map<UserDto>(user);
+    }
+}
+```
+
+### Unit of Work Pattern
+
+**EN**: Maintains a list of objects affected by a business transaction and coordinates writing changes.
+
+**VI**: Duy trì danh sách các objects bị ảnh hưởng bởi một business transaction và điều phối việc ghi thay đổi.
+
+### CQRS (Command Query Responsibility Segregation)
+
+**EN**: Optional pattern for separating read and write operations.
+
+**VI**: Pattern tùy chọn để tách biệt các operations đọc và ghi.
+
+## Best Practices / Thực Hành Tốt
+
+### 1. Dependency Injection
+
+```csharp
+// EN: Register services in Program.cs
+// VI: Đăng ký services trong Program.cs
+builder.Services.AddScoped<IUserRepository, UserRepository>();
+builder.Services.AddScoped<IUserService, UserService>();
+```
+
+### 2. Async/Await
+
+```csharp
+// EN: Always use async for I/O operations
+// VI: Luôn dùng async cho I/O operations
+public async Task<User> GetUserAsync(Guid id)
+{
+    return await _context.Users.FindAsync(id);
+}
+```
+
+### 3. Error Handling
+
+```csharp
+// EN: Create custom exceptions
+// VI: Tạo custom exceptions
+public class NotFoundException : Exception
+{
+    public NotFoundException(string message) : base(message) { }
+}
+
+// EN: Global exception handler middleware
+// VI: Middleware xử lý exception toàn cục
+public class ExceptionMiddleware
+{
+    // ... implementation
+}
+```
+
+### 4. Validation
+
+```csharp
+// EN: Use FluentValidation for input validation
+// VI: Dùng FluentValidation để validate input
+public class CreateUserDtoValidator : AbstractValidator<CreateUserDto>
+{
+    public CreateUserDtoValidator()
+    {
+        RuleFor(x => x.Email).NotEmpty().EmailAddress();
+        RuleFor(x => x.Password).MinimumLength(8);
+    }
+}
+```
+
+## Testing Strategy / Chiến Lược Testing
+
+**EN**: 
+- **Unit Tests**: Test business logic in isolation
+- **Integration Tests**: Test layer interactions
+- **E2E Tests**: Test complete workflows
+
+**VI**:
+- **Unit Tests**: Test business logic độc lập
+- **Integration Tests**: Test tương tác giữa các lớp
+- **E2E Tests**: Test toàn bộ workflows

+## Architecture Patterns / Mẫu Kiến Trúc
+
+**EN**: This template follows Clean Architecture principles:
+1. **API Layer**: Controllers, middleware, configuration
+2. **Application Layer**: Business logic, DTOs, services
+3. **Domain Layer**: Entities, interfaces, domain logic
+4. **Infrastructure Layer**: Data access, external services
+
+**VI**: Template này tuân theo nguyên tắc Clean Architecture:
+1. **Lớp API**: Controllers, middleware, cấu hình
+2. **Lớp Application**: Business logic, DTOs, services
+3. **Lớp Domain**: Entities, interfaces, domain logic
+4. **Lớp Infrastructure**: Truy cập dữ liệu, external services
+
+## Best Practices / Thực Hành Tốt
+
+1. **Dependency Injection**: Use built-in DI container / Sử dụng DI container có sẵn
+2. **Async/Await**: Use async methods for I/O operations / Dùng async cho I/O
+3. **Logging**: Use ILogger for structured logging / Dùng ILogger
+4. **Validation**: Use FluentValidation for input validation / Dùng FluentValidation
+5. **Error Handling**: Implement global exception middleware / Middleware xử lý lỗi toàn cục
