## Overview

This is a Django learning-management site with a separate Node.js WebRTC signaling service. The main workflow is account registration or sign-in, then course/class discovery and participation; teachers can manage classes and notes, while learners can browse or download learning materials. Course checkout is a separate example flow that records a payment and redirects through SSLCOMMERZ. The README also documents real-time calls. Some routing and WebRTC relationships are supported by the README or source index rather than inspected implementations; the graph does not assume more detailed signaling or deployment behavior.

Main entry points: [`MyProject/urls.py`](https://github.com/sakib-hossaine/let-s-learn-django-online-education-system/blob/main/MyProject/urls.py) (Django Site), [`users/views.py`](https://github.com/sakib-hossaine/let-s-learn-django-online-education-system/blob/main/users/views.py) (Accounts and Profiles), [`notes/views.py`](https://github.com/sakib-hossaine/let-s-learn-django-online-education-system/blob/main/notes/views.py) (Notes Library), [`courses/views.py`](https://github.com/sakib-hossaine/let-s-learn-django-online-education-system/blob/main/courses/views.py) (Payment Flow)
