## Overview

This repository is a CodeIgniter-based multilingual, multi-vendor shopping platform. The main customer journey is browsing products, managing a cart, and checking out; the platform also provides vendor and administrator workflows, content management, and a REST API. The graph preserves those documented capabilities, but many application internals were not sampled, so uncertain controller-to-model and payment links are shown as unverified rather than asserted. The framework runtime is included as the internal request-routing layer.

Main entry points: [`application/config/database.php`](https://github.com/kirilkirkov/ecommerce-codeigniter-bootstrap/blob/master/application/config/database.php) (Configured database), [`application/controllers/Checkout.php`](https://github.com/kirilkirkov/ecommerce-codeigniter-bootstrap/blob/master/application/controllers/Checkout.php) (Checkout and payments), [`application/modules/admin/controllers/ecommerce/Orders.php`](https://github.com/kirilkirkov/ecommerce-codeigniter-bootstrap/blob/master/application/modules/admin/controllers/ecommerce/Orders.php) (Order administration), [`application/controllers/Api/Products.php`](https://github.com/kirilkirkov/ecommerce-codeigniter-bootstrap/blob/master/application/controllers/Api/Products.php) (Products API)
