-# FastAPI Application
+# Simple Todo App
 
-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 todos by completion status
+- Health check endpoint
+- Database migrations with Alembic
+- CORS enabled for all origins
+
+## Project Structure
+

+
+## Getting Started
+
+### Prerequisites
+
+- Python 3.8 or higher
+
+### Installation
+
+1. Clone the repository:
+
+```bash
+git clone <repository-url>
+cd simpletodoapp
+```
+
+2. Install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+3. Run database migrations:
+
+```bash
+alembic upgrade head
+```
+
+4. Start the application:
+
+```bash
+uvicorn main:app --host 0.0.0.0 --port 8000 --reload
+```
+
+The API will be available at http://localhost:8000
+
+## API Documentation
+
+Once the application is running, you can access the API documentation at:
+
+- Swagger UI: http://localhost:8000/docs
+- ReDoc: http://localhost:8000/redoc
+
+## API Endpoints
+
+### Todo Endpoints
+
+- `GET /api/v1/todos` - Get all todos (with optional filtering)
+- `POST /api/v1/todos` - Create a new todo
+- `GET /api/v1/todos/{todo_id}` - Get a specific todo
+- `PATCH /api/v1/todos/{todo_id}` - Update a todo
+- `DELETE /api/v1/todos/{todo_id}` - Delete a todo
+
+### Health Endpoint
+
+- `GET /health` - Check application health
+
+## Environment Variables
+
+The application uses the following environment variables:
+
+- None required for basic setup (SQLite database is stored in `/app/storage/db/db.sqlite`)
+
