## Overview

e-PCOS is a PCOS-awareness and online-survey web application. Visitors register or sign in, use customer features such as appointments and surveys, and receive rendered pages or responses; administrators manage users, content, surveys, appointments, and reports. The graph distinguishes those domain areas and includes CodeIgniter’s request-routing runtime as an internal layer. The README documents email notifications, a chatbot, and backup/restore, but sampled source only confirms the restore route; implementation details for those features are therefore not inferred.

Main entry points: [`app/Config/Routes.php`](https://github.com/vin0414/e-pcos/blob/main/app/Config/Routes.php) (Application routes), [`app/Controllers/ManageController.php`](https://github.com/vin0414/e-pcos/blob/main/app/Controllers/ManageController.php) (Admin management), [`app/Controllers/Customer.php`](https://github.com/vin0414/e-pcos/blob/main/app/Controllers/Customer.php) (Customer actions), [`app/Models`](https://github.com/vin0414/e-pcos/tree/main/app/Models) (Application data models)
