-# FastAPI Application
+# Simple Todo App
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A RESTful API for managing todo items, built with FastAPI and SQLite.
+
+## Features
+
+- Create, read, update, and delete todo items
+- SQLite database with SQLAlchemy ORM
+- Alembic for database migrations
+- Health check endpoint
+- API documentation with Swagger UI
+
+## Prerequisites
+
+- Python 3.9+
+- Pip package manager
+
+## Project Structure
+
+```

+└── requirements.txt   # Project dependencies
+```
+
+## Installation
+
+1. Clone the repository:
+```bash
+git clone <repository-url>
+cd simpletodoapp
+```
+
+2. Install the dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+## Running the Application
+
+Start the application with Uvicorn:
+
+```bash
+uvicorn main:app --reload
+```
+
+The API will be available at `http://localhost:8000`.
+
+## API Documentation
+
+Once the application is running, you can access the interactive API documentation:
+
+- Swagger UI: `http://localhost:8000/docs`
+- ReDoc: `http://localhost:8000/redoc`
+
+## API Endpoints
+
+### Health Check
+- `GET /health` - Check the health of the service
+
+### Todo Operations
+- `POST /api/todos` - Create a new todo item
+- `GET /api/todos` - Get all todo items
+- `GET /api/todos/{todo_id}` - Get a specific todo item
+- `PUT /api/todos/{todo_id}` - Update a todo item
+- `DELETE /api/todos/{todo_id}` - Delete a todo item
