What is Drupal?

Drupal is a free software package that allows you to easily organize, manage and publish your content, with an endless variety of customization (https://drupal.org/about) and powering over 1 million websites world wide.  The community is passionate about sharing and contributing to the larger effort and helps support the likes of whitehouse.govData.gov.uk and many others (http://www.drupalshowcase.com/) from large to small nimble organizations.  To get a handle on drupal concepts we'll refer you to this site: https://drupal.org/documentation/concepts
