## Overview

This is a minimal Express admission-system application: it connects to MongoDB, serves a rendered welcome page, and exposes separate admin, institute, and user route roots. The sampled routes return section messages only; no admission workflows or data models are present in the supplied source. The landing template is rendered by the application, but its contents and component usage were not sampled.

Main entry points: [`api/index.js`](https://github.com/mhgkhan/iadmissionsystem/blob/main/api/index.js) (Express app), [`api/routes/admin.route.js`](https://github.com/mhgkhan/iadmissionsystem/blob/main/api/routes/admin.route.js) (Admin route), [`api/routes/institute.route.js`](https://github.com/mhgkhan/iadmissionsystem/blob/main/api/routes/institute.route.js) (Institute route), [`api/routes/user.route.js`](https://github.com/mhgkhan/iadmissionsystem/blob/main/api/routes/user.route.js) (User route)
