## Overview

AgroBridge is a farmer-facing market-linkage and decision-support platform: farmers manage produce, assess markets and quality, compare buyer offers after transport costs, and explore logistics and transactions. The React app selects the user journey; a FastAPI backend exposes prediction, grading, pooling, and chatbot routers. The README describes broader capabilities, but many page and API implementations were not sampled, so their internal wiring is not inferred.

Main entry points: [`frontend/src/App.jsx`](https://github.com/harshm13/agrobridge-sih26132/blob/main/frontend/src/App.jsx) (App and navigation), [`backend/main.py`](https://github.com/harshm13/agrobridge-sih26132/blob/main/backend/main.py) (FastAPI application), [`backend/api/chatbot.py`](https://github.com/harshm13/agrobridge-sih26132/blob/main/backend/api/chatbot.py) (Chatbot endpoint), [`frontend/src/pages/FarmerOnboarding.jsx`](https://github.com/harshm13/agrobridge-sih26132/blob/main/frontend/src/pages/FarmerOnboarding.jsx) (Farmer onboarding)
