Implement Task Manager API with FastAPI and SQLite

Create a full-featured task management API with the following components:
- RESTful CRUD operations for tasks
- Task status and priority management
- SQLite database with SQLAlchemy ORM
- Alembic migrations
- Health check endpoint
- Comprehensive API documentation

-# FastAPI Application
+# Task Manager API
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A RESTful API for managing tasks built with FastAPI and SQLite.
+
+## Features
+
+- Create, read, update, and delete tasks
+- Filter tasks by status and title
+- Task prioritization
+- Due date management
+- Health check endpoint for monitoring
+- Comprehensive API documentation
+
+## Tech Stack
+
+- **FastAPI**: Modern, fast web framework for building APIs
+- **SQLAlchemy**: SQL toolkit and Object-Relational Mapping
+- **Alembic**: Database migration tool
+- **SQLite**: Lightweight, file-based database
+- **Pydantic**: Data validation and settings management
+- **Uvicorn**: ASGI server
+

+
+## Getting Started
+
+### Prerequisites
+
+- Python 3.8+
+
+### Installation
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/yourusername/taskmanagerapi.git
+   cd taskmanagerapi
+   ```
+
+2. Install dependencies:
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+3. Run the application:
+   ```bash
+   uvicorn main:app --reload
+   ```
+
+4. Access the API at `http://localhost:8000`
+
+5. Access the API documentation at `http://localhost:8000/docs` or `http://localhost:8000/redoc`
+
+## API Endpoints
+
+### Health Check
+
+- `GET /api/v1/health`: Check the health of the application
+
+### Tasks
+
+- `GET /api/v1/tasks`: List all tasks
+- `POST /api/v1/tasks`: Create a new task
+- `GET /api/v1/tasks/{id}`: Get a specific task
+- `PUT /api/v1/tasks/{id}`: Update a specific task
+- `DELETE /api/v1/tasks/{id}`: Delete a specific task
+
+## Task Model
+
+```json
+{
+  "id": 1,
+  "title": "Complete project",
+  "description": "Finish the project by the deadline",
+  "status": "todo",
+  "priority": "high",
+  "due_date": "2023-12-31T23:59:59",
+  "created_at": "2023-09-01T12:00:00",
+  "updated_at": "2023-09-01T12:00:00"
+}
+```
+
+## Filtering Tasks
+
+- By status: `GET /api/v1/tasks?status=todo`
+- By title: `GET /api/v1/tasks?title=project`
+- Pagination: `GET /api/v1/tasks?skip=0&limit=10`
