This document provides an overview of developing web applications using the Kohana MVC framework. It discusses key Kohana features like its use of MVC and HMVC patterns. It demonstrates how to set up Kohana, configure databases, create controllers to read, insert and update database records, and use models and ORM. It also shows how to hide the index.php file and make nested requests using HMVC.
