## Overview

This repository is a small FastAPI backend skeleton, not yet a RAG system: it exposes health and sample-data endpoints plus a template-based home route. The home route references `templates/index.html`, which is not present in the supplied file tree, so the template’s availability cannot be confirmed.

Main entry points: [`main.py`](https://github.com/charles-ndungu/rag_project/blob/main/main.py) (FastAPI app)
