This document discusses feature-driven development in Drupal using the Features module. It describes how Features allows encapsulating reusable parts of a Drupal site like content types, views, and configurations into modules that can then be exported, version controlled, and shared. It provides guidance on setting up Features and creating a new feature to extract components into a reusable feature module.
