## Overview

CommunityHub is a MERN learning-content platform: members discover courses, authenticate, purchase/enroll, study course sections, and submit ratings; instructors create and manage courses and review dashboard insights. The graph separates client workflows, server domains, persistence, and integrations. README capabilities supplement the sampled code; details of unsampled route/controller wiring are represented only where the server entry point documents route mounting.

Main entry points: [`src/App.jsx`](https://github.com/thesuhriday7/communityhub-opensource/blob/main/src/App.jsx) (Web app routes), [`src/services/operations/courseDetailsAPI.js`](https://github.com/thesuhriday7/communityhub-opensource/blob/main/src/services/operations/courseDetailsAPI.js) (API operations), [`Server/index.js`](https://github.com/thesuhriday7/communityhub-opensource/blob/main/Server/index.js) (API server), [`Server/models/Course.js`](https://github.com/thesuhriday7/communityhub-opensource/blob/main/Server/models/Course.js) (Course records)
