## Overview

This is a MERN irrigation-register application for tracking farmers, irrigation work, payments, and outstanding dues. Admins manage farmer records and enter or edit irrigation and payment data; farmers can look up their own record by phone. The React app calls the API client, which sends requests to the Express routes; those routes validate and calculate costs, summaries, and dashboard totals while using Mongoose models backed by MongoDB. The README documents the main capabilities; some UI and API implementation details are inferred from the available excerpts.
