vickykumar-2003/LMS-MERN ? reverse-engineered prompt

Build me a simple learning management system where teachers and students can sign in and use the app easily.

I want a clean frontend and a working backend, with separate areas for admin, teachers, and students. Teachers should be able to create courses, add lessons or materials, and track student progress. Students should be able to browse their courses, open lessons, see assignments, and check what they have completed. Include basic login and signup, plus a dashboard that feels easy to use.

Make the app feel polished and modern, with sensible navigation and responsive pages that work on desktop and mobile. Use the usual MERN style setup for the full stack, and wire up the backend so the main features actually work end to end. If you need to look up current docs online, go ahead. Please also set it up so it is easy to run locally and extend later with more LMS features.
