-# FastAPI Application
+# Task Manager API
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A comprehensive Task Manager API built with FastAPI and SQLite, providing full CRUD operations for task management with filtering, search, and statistics capabilities.
+
+## Features
+
+- ✅ **Task Management**: Create, read, update, and delete tasks
+- 🔍 **Advanced Filtering**: Filter tasks by status, priority, and search text
+- 📊 **Statistics**: Get task count summaries by status
+- 🚀 **FastAPI Framework**: Modern, fast web framework with automatic API documentation
+- 💾 **SQLite Database**: Lightweight, serverless database with Alembic migrations
+- 📝 **Comprehensive API Documentation**: Auto-generated OpenAPI/Swagger docs
+- 🌐 **CORS Support**: Cross-origin resource sharing enabled
+- ⚡ **Health Checks**: Built-in health monitoring endpoint
+
+## Task Properties
+
+Each task includes:
+- **Title**: Task name (required, max 255 characters)
+- **Description**: Optional detailed description
+- **Status**: `pending`, `in_progress`, or `completed`
+- **Priority**: `low`, `medium`, or `high`
+- **Due Date**: Optional deadline
+- **Timestamps**: Auto-generated creation and update times
+
+## API Endpoints
+
+### Tasks
+- `GET /tasks/` - List all tasks with optional filtering
+- `POST /tasks/` - Create a new task
+- `GET /tasks/{id}` - Get a specific task
+- `PUT /tasks/{id}` - Update a task
+- `DELETE /tasks/{id}` - Delete a task
+- `GET /tasks/stats/summary` - Get task statistics
+
+### System
+- `GET /` - API information and links
+- `GET /health` - Health check endpoint
+- `GET /docs` - Interactive API documentation (Swagger UI)
+- `GET /redoc` - Alternative API documentation
+- `GET /openapi.json` - OpenAPI schema
+
+## Quick Start
+
+1. **Install Dependencies**
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+2. **Run Database Migrations**
+   ```bash
+   alembic upgrade head
+   ```
+
+3. **Start the Server**
+   ```bash
+   uvicorn main:app --reload
+   ```
+
+4. **Access the Application**
+   - API: http://localhost:8000
+   - Documentation: http://localhost:8000/docs
+   - Health Check: http://localhost:8000/health
+
+## API Usage Examples
+
+### Create a Task
+```bash
+curl -X POST "http://localhost:8000/tasks/" \
+     -H "Content-Type: application/json" \
+     -d '{
+       "title": "Complete project documentation",
+       "description": "Write comprehensive README and API docs",
+       "priority": "high",
+       "status": "pending"
+     }'
+```
+
+### Get All Tasks
+```bash
+curl "http://localhost:8000/tasks/"
+```
+
+### Filter Tasks
+```bash
+# Get high priority tasks
+curl "http://localhost:8000/tasks/?priority=high"
+
+# Get completed tasks
+curl "http://localhost:8000/tasks/?status=completed"
+
+# Search tasks
+curl "http://localhost:8000/tasks/?search=documentation"
+```
+
+### Update a Task
+```bash
+curl -X PUT "http://localhost:8000/tasks/1" \
+     -H "Content-Type: application/json" \
+     -d '{
+       "status": "completed"
+     }'
+```
+
+### Get Task Statistics
+```bash
+curl "http://localhost:8000/tasks/stats/summary"
+```
+
+## Database
+
+The application uses SQLite with the following configuration:
+- **Database Location**: `/app/storage/db/db.sqlite`
+- **Migration Tool**: Alembic
+- **Schema Management**: Automatic table creation and migrations
+
+## Environment Variables
+
+Currently, no environment variables are required. The application uses SQLite with a fixed path for simplicity.
+
