This document provides an overview of web application development using the Kohana MVC framework. It discusses key features of Kohana like its use of MVC and HMVC patterns. It also demonstrates how to set up Kohana, configure the framework, make requests to controllers, read and write data to a database using the ORM, and use HMVC to include views within other views or controllers. The goal is to introduce the Kohana framework and demonstrate basic usage for building web applications.

->as_array();
$this->request->response =
View::factory('list', $data);
}
