## Overview

This is a CodeIgniter web application for a neighborhood-oriented request portal, with public registration, login, news and contact pages plus an administrative area for users, requests, neighborhoods and reference data. The likely user journey is to register or sign in, provide address details, and use request-related functionality; administrators maintain requests and the data that classifies them. The tree establishes these domains, but README content is absent and most controller/model implementations were not sampled, so uncertain runtime connections are omitted.

Main entry points: [`application/config/routes.php`](https://github.com/breno-n/ctp/blob/master/application/config/routes.php) (Route mapping), [`application/config/database.php`](https://github.com/breno-n/ctp/blob/master/application/config/database.php) (Application database), [`application/controllers/admin/Requisicoes.php`](https://github.com/breno-n/ctp/blob/master/application/controllers/admin/Requisicoes.php) (Request admin), [`application/controllers/Home.php`](https://github.com/breno-n/ctp/blob/master/application/controllers/Home.php) (Home page)
