## Overview

This is a small command-line Gemini chatbot. The user enters messages; `main.py` handles exit and clear commands, keeps conversation history in memory, builds a prompt, calls Gemini, and displays the response. Startup loads the API key from the environment (with `.env` loading documented and shown in source). The runtime is contained in one file; the graph separates its meaningful responsibilities. No separate storage or service layer is present.

Main entry points: [`main.py`](https://github.com/inamurrehman-ai/gemini-python-chatbot/blob/main/main.py) (Chat loop)
