## Overview

Zeedone is a web e-learning platform: users access video lessons, enroll in courses, track progress, and use subscriptions to unlock paid classes. Registration and login establish accounts; authenticated API routes support profile, course, tutor, subscription, and notification functions. The README also describes social discussion/comment interactions, but their implementation is not evident in the sampled files, so no discussion flow is drawn. The frontend and notification route are represented from the tree; their internal behavior was not sampled.

Main entry points: [`server.js`](https://github.com/sudamala07/zeedone/blob/main/server.js) (Express app), [`routes/courses.js`](https://github.com/sudamala07/zeedone/blob/main/routes/courses.js) (Course routes), [`routes/auth.js`](https://github.com/sudamala07/zeedone/blob/main/routes/auth.js) (Auth routes), [`middleware/auth.js`](https://github.com/sudamala07/zeedone/blob/main/middleware/auth.js) (Auth middleware)
