Drupal is an open source CMS framework written in PHP. *IMPORTANT* Rather than using this tag, consider posting your question directly on https://drupal.stackexchange.com/. Also, because of substantial differences between major versions, consider using either the drupal-6, drupal-7 or drupal-8 tags.
Drupal is a highly configurable open-source Content Management System (cms), and Web application framework. Questions here can often be answered in a programmatic manner, or through the use of modules and configurations. Backed by a very active developer community, the Drupal official ecosystem currently (Aug 2018) shows some impressive numbers:
- 2,655 Themes - Themes allow you to change the look and feel of your Drupal site. You can use themes contributed by others or create your own to share with the community;
- 41,159 Modules - Extend and customize Drupal functionality with contributed modules;
- 1,236 Distributions - Distributions, also referred to as installation profiles, provide site features and functions for a specific type of site as a single download containing Drupal core, contributed modules, themes, and pre-defined configuration. They make it possible to quickly set up a complex, use-specific site in fewer steps than if installing and configuring elements individually:
- 100+ Translations - Drupal core is just one of the 20,601 projects translated on the official server.
The latest version with official releases is Drupal 8. ( Drupal 7 is still largely used); For more details about the different versions, refer to Releases for Drupal Core
Drupal questions can also be asked on #drupal on the FreeNode IRC network, or on the drupal.org support forums.
Drupal Answers is a dedicated Stack Exchange site for Drupal. You are invited to use it for any questions specific to Drupal which are outside the scope of Stack Overflow.
Each major release of Drupal is not completely compatible with the previous; hence, the importance of using the version tags (e.g. drupal-5, drupal-6, drupal-7, drupal-8) whenever appropriate.
