+# AniWorld FastAPI Documentation
+
+## Overview
+
+AniWorld has been successfully migrated from Flask to FastAPI, providing improved performance, automatic API documentation, and modern async support.
+
+## Accessing API Documentation
+
+### Interactive API Documentation
+
+FastAPI automatically generates interactive API documentation that you can access at:
+
+-   **Swagger UI**: `http://localhost:8000/docs`
+-   **ReDoc**: `http://localhost:8000/redoc`
+
+These interfaces allow you to:
+
+-   Browse all available endpoints
+-   View request/response schemas
+-   Test API endpoints directly from the browser
+-   Download OpenAPI schema
+
+### OpenAPI Schema
+
+The complete OpenAPI 3.0 schema is available at:
+
+-   **JSON Format**: `http://localhost:8000/openapi.json`
+
+## Authentication
+
+### Master Password Authentication
+
+AniWorld uses a simple master password authentication system with JWT tokens.
+
+#### Login Process
+
+1. **POST** `/auth/login`
+    - Send master password in request body
+    - Receive JWT token in response
+    - Token expires in 24 hours
+
+```json
+{
+    "password": "your_master_password"
+}
+```
+
+Response:
+
+```json
+{
+    "success": true,
+    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
+    "message": "Login successful"
+}
+```
+
+#### Using Authentication Token
+
+Include the token in the `Authorization` header for authenticated requests:
+
+```
+Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...
+```
+
+## API Endpoints

+
+```json
+{
+  "success": true,
+  "data": {...},
+  "message": "Operation completed successfully"
+}
+```
+
+### Error Responses
+
+Error responses include detailed error information:
+
+```json
+{
+  "success": false,
+  "error": "Error description",
+  "code": "ERROR_CODE",
+  "details": {...}
+}
+```
+
+## Status Codes
+
+-   **200 OK** - Successful operation

+# AniWorld Project Overview
+
+## 📁 Folder Structure
+
+The project follows a modular, layered architecture inspired by MVC and Clean Architecture principles. The main directories are:
+
+```
+src/
+  controllers/    # API endpoints and route handlers
+  services/       # Business logic and orchestration
+  repositories/   # Data access layer (DB, external APIs)
+  schemas/        # Pydantic models for validation/serialization
+  utils/          # Utility functions and helpers
+  config/         # Configuration management (env, settings)
+tests/
+  unit/           # Unit tests for core logic
+  integration/    # Integration tests for end-to-end scenarios
+```
+
+## 🏗️ Architecture
+
+- **MVC & Clean Architecture:** Separation of concerns between controllers (views), services (business logic), and repositories (data access).
+- **Dependency Injection:** Used for service/repository wiring, especially with FastAPI's `Depends`.
+- **Event-Driven & Microservices Ready:** Modular design allows for future scaling into microservices or event-driven workflows.
+- **Centralized Error Handling:** Custom exceptions and error middleware for consistent API responses.
+
+## 🧰 Used Libraries & Frameworks
+
+- **Python** (PEP8, PEP257, type hints)
+- **FastAPI**: High-performance async web API framework
+- **Pydantic**: Data validation and serialization
+- **Poetry**: Dependency management and packaging
+- **dotenv / os.environ**: Environment variable management
+- **logging / structlog**: Structured logging
+- **pytest / unittest**: Testing frameworks
+- **aiohttp**: Async HTTP client (where needed)
+- **SQLAlchemy / asyncpg / databases**: Database ORM and async drivers (if present)
+- **Prometheus**: Metrics endpoint integration
+- **Other**: As required for integrations (webhooks, third-party APIs)
+
+## 🧩 Patterns & Conventions
+
+- **Repository Pattern:** All data access is abstracted via repositories.
+- **Service Layer:** Business logic is encapsulated in services, not controllers.
+- **Pydantic Models:** Used for all input/output validation.
+- **Async Endpoints:** All I/O-bound endpoints are async for scalability.
+- **Environment Configuration:** All secrets/configs are loaded from `.env` or environment variables.
+- **Logging:** All logs are structured and configurable.
+- **Testing:** High coverage with fixtures and mocks for external dependencies.
+
+## 🛡️ Security & Performance
+
+- **JWT Authentication:** Secure endpoints with token-based auth.
+- **Input Validation:** All user input is validated via Pydantic.
+- **No Hardcoded Secrets:** All sensitive data is externalized.
+- **Performance Optimization:** Async I/O, caching, and profiling tools.
+
+## 🎨 UI & CLI
+
+- **Theme Support:** Light/dark/auto modes.
+- **Accessibility:** Screen reader, color contrast, keyboard shortcuts.
+- **CLI Tool:** For bulk operations, scanning, and management.

+-   Type hints are crucial for FastAPI functionality
+
+### Common Gotchas:
+
+-   FastAPI doesn't have built-in session support (use external library if needed)
+-   Template responses need explicit media_type for HTML
+-   Static file mounting needs to be configured explicitly
+-   Request object structure is different from Flask
+
+### Performance Considerations:
+
+-   FastAPI is generally faster than Flask
+-   Consider using async functions for I/O operations
+-   Use background tasks for long-running operations
+-   Implement proper caching strategies

-  - Review logging configuration and levels
-
-- [ ] **Integration Testing**: Add missing test coverage
-  - Test complete request/response cycles
-  - Verify authentication flow end-to-end
-  - Test error scenarios and edge cases
-  - Add load testing for critical endpoints
-
-### Common Bug Patterns to Check
-
-#### FastAPI Specific Issues
-- [ ] **Async/Await Usage**: Review asynchronous implementation
-  - Check if async endpoints are properly awaited
-  - Verify database operations use async patterns
-  - Ensure proper async context management
-  - Review thread safety in async operations
-
-- [ ] **Dependency Scope**: Review dependency lifecycles
-  - Check if singleton services are properly configured
-  - Verify database connections are not leaked
-  - Ensure proper cleanup in dependency teardown
-  - Review request-scoped vs application-scoped dependencies
-
-#### Data Consistency Issues
-- [ ] **Race Conditions**: Check for concurrent access issues
-  - Review critical sections that modify shared data
-  - Check for proper locking mechanisms
-  - Verify atomic operations for data updates
-  - Review transaction isolation levels
-
-- [ ] **Data Validation**: Comprehensive input validation
-  - Check for missing required field validation
-  - Verify proper format validation (email, URL, etc.)
-  - Ensure proper range validation for numeric fields
-  - Review business logic validation rules
-
-## Authentication System Design
-
-### Simple Master Password Authentication
-- **No User Registration**: Single master password for the entire application
-- **No Email System**: No email verification or password reset via email
-- **Environment Configuration**: Master password hash stored securely in .env
-- **JWT Tokens**: Stateless authentication using JWT for API access
-- **Session Management**: Client-side token storage and management
-
-### Authentication Flow
-1. **Login**: POST `/auth/login` with master password
-2. **Token**: Receive JWT token for subsequent requests
-3. **Authorization**: Include token in Authorization header for protected endpoints
-4. **Verification**: Use `/auth/verify` to check token validity
-5. **Logout**: Client removes token (stateless logout)
-
-### Security Features
-- Password hashing with SHA-256 and salt
-- Configurable token expiry
-- JWT secret from environment variables
-- No sensitive data in source code
-
-## Priority Order
-1. **Critical Priority**: Fix API implementation bugs and security vulnerabilities
-2. **High Priority**: Complete core functionality (Anime Controller, Episode Controller)
-3. **Medium Priority**: Performance optimizations (Database Service, Caching)
-4. **Low Priority**: Enhanced features and testing
-
-## Notes
-- ✅ Authentication system uses simple master password (no email/user management)
-- Follow the repository pattern consistently across all data access
-- Use dependency injection for all service dependencies
-- Implement proper logging for all controller actions
-- Add input validation using Pydantic models for all endpoints
-- Use the `get_current_user` dependency for protecting endpoints that require authentication
-- All API endpoints should follow RESTful conventions
-- Implement proper OpenAPI documentation for all endpoints
-- Use environment variables for all configuration values
-- Follow Python typing best practices with proper type hints

+
+    A comprehensive FastAPI-based application for managing anime series and episodes.
+
+    ### Features
+
+    * **Series Management**: Search, track, and manage anime series
+    * **Episode Tracking**: Monitor missing episodes and download progress  
+    * **Authentication**: Secure master password authentication with JWT tokens
+    * **Real-time Updates**: WebSocket support for live progress tracking
+    * **File Management**: Automatic file scanning and organization
+    * **Download Queue**: Queue-based download management system
+
+    ### Authentication
+
+    Most endpoints require authentication using a master password.
+    Use the `/auth/login` endpoint to obtain a JWT token, then include it
+    in the `Authorization` header as `Bearer <token>`.
