-# FastAPI Application
+# Simple Todo Application
 
-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 SQLAlchemy.
+
+## Features
+
+- Create, read, update, and delete todo items
+- Database migrations with Alembic
+- SQLite database
+- Health check endpoint
+
+## Project Structure
+
+```

+```
+
+## Installation
+
+1. Clone the repository:
+```bash
+git clone <repository-url>
+cd simpletodoapplication
+```
+
+2. Install dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+## Running the Application
+
+Start the application using Uvicorn:
+```bash
+uvicorn main:app --reload
+```
+
+The API will be available at http://localhost:8000.
+
+API documentation is automatically generated and available at:
+- http://localhost:8000/docs (Swagger UI)
+- http://localhost:8000/redoc (ReDoc)
+
+## API Endpoints
+
+- `GET /health` - Health check endpoint
+- `GET /api/v1/todos` - List all todos
+- `POST /api/v1/todos` - Create a new todo
+- `GET /api/v1/todos/{todo_id}` - Get a specific todo
+- `PUT /api/v1/todos/{todo_id}` - Update a todo
+- `DELETE /api/v1/todos/{todo_id}` - Delete a todo
+
+## Database Migrations
+
+To apply migrations:
+```bash
+alembic upgrade head
+```
+
+This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
