## Overview

DoctorCare is a web application for discovering doctors and specialties, booking appointments, and managing care; it also provides doctor and administrator workflows. The principal flow is a visitor entering the web routes, browsing doctors, selecting an appointment, and receiving booking information. Authenticated doctors manage schedules and appointments, while administrators manage doctors, users, posts, and schedules. The README documents these capabilities; some view paths it names are not present in the supplied tree. Edges follow the route declarations, sampled imports, and documented flows; unsampled implementation details are not inferred.

Main entry points: [`src/controllers/adminController.js`](https://github.com/ngoc-quyen/datn/blob/master/src/controllers/adminController.js) (Admin pages), [`src/models/index.js`](https://github.com/ngoc-quyen/datn/blob/master/src/models/index.js) (Sequelize models), [`src/routes/web.js`](https://github.com/ngoc-quyen/datn/blob/master/src/routes/web.js) (Web routes), [`src/controllers/homeController.js`](https://github.com/ngoc-quyen/datn/blob/master/src/controllers/homeController.js) (Public pages)
