This document discusses integrating CiviCRM with content management systems (CMS) like Joomla, WordPress, and Drupal. It describes how a CMS integration allows embedding CiviCRM pages within a website with the same look and feel. Key features of integrations include linking contact records to user accounts, permissions, and extending functionality through plugins/modules. Drupal has the strongest integration through built-in blocks, access controls, and synchronization of memberships. Determining the best CMS depends on factors like required features, administration needs, and budget.
