-# FastAPI Application
+# Simple TODO Application
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A simple TODO application built with FastAPI and SQLite.
+
+## Features
+
+- Create, read, update, and delete TODO items
+- Filter TODO items by completion status
+- Health check endpoint
+
+## Tech Stack
+
+- FastAPI: Web framework for building APIs
+- SQLAlchemy: ORM for database interactions
+- Pydantic: Data validation and settings management
+- Alembic: Database migration tool
+- SQLite: Lightweight relational database
+- Uvicorn: ASGI server for running the application
+
+## Project Structure

+
+## Running the Application
+
+1. Install dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+2. Run database migrations:
+```bash
+alembic upgrade head
+```
+
+3. Start the application:
+```bash
+uvicorn main:app --host 0.0.0.0 --port 8000 --reload
+```
+
+4. Visit the API documentation:
+   - Swagger UI: http://localhost:8000/docs
+   - ReDoc: http://localhost:8000/redoc
+
+## API Endpoints
+
+### Health Check
+- `GET /health` - Check API and database status
+
+### Todo Operations
+- `GET /api/todos` - List all todos (can filter by completion status)
+- `POST /api/todos` - Create a new todo
+- `GET /api/todos/{todo_id}` - Get a specific todo
+- `PUT /api/todos/{todo_id}` - Update a todo
+- `DELETE /api/todos/{todo_id}` - Delete a todo
+
+## Example Usage
+
+### Create a Todo
+
+```bash
+curl -X POST http://localhost:8000/api/todos \
+  -H "Content-Type: application/json" \
+  -d '{"title": "Learn FastAPI", "description": "Complete FastAPI tutorial", "completed": false}'
+```
+
+### Get All Todos
+
+```bash
+curl http://localhost:8000/api/todos
+```
+
+### Get Completed Todos
+
+```bash
+curl http://localhost:8000/api/todos?completed=true
+```
+
+### Update a Todo
+
+```bash
+curl -X PUT http://localhost:8000/api/todos/1 \
+  -H "Content-Type: application/json" \
+  -d '{"completed": true}'
+```
+
+### Delete a Todo
+
+```bash
+curl -X DELETE http://localhost:8000/api/todos/1
+```
