-# FastAPI Application
+# Simple Todo App
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A simple REST API for managing todos built with FastAPI and SQLite.
+
+## Features
+
+- Create, read, update, and delete todos
+- SQLite database with SQLAlchemy ORM
+- Database migrations with Alembic
+- Health check endpoint
+- API documentation (Swagger UI and ReDoc)
+
