What is Drupal

Drupal is a free and open source Content Management System built on PHP, with a modular design allowing features to be added and removed by installing and uninstalling modules, and allowing the entire look and feel of the website to be changed by installing and uninstalling themes. That allows organizing, managing and publishing your content.
