Contributed is a term used to describe modules, themes, and other components of Drupal that are created by the community and made available for free. These components are not part of the core Drupal software, but are instead created by individuals or organizations to extend the functionality of Drupal. Contributed modules, themes, and other components are available for download from the Drupal.org website.
Contributed modules are pieces of code that add new features and functionality to Drupal. They can be used to add features such as forums, image galleries, and e-commerce capabilities. Contributed themes are used to change the look and feel of a Drupal website. They can be used to customize the colors, fonts, and layout of a website. Other contributed components include translations, which allow Drupal websites to be displayed in different languages, and distributions, which are pre-packaged collections of modules and themes that can be used to quickly set up a Drupal website.
Contributed components are created and maintained by the Drupal community. They are released under open source licenses, which allow anyone to use, modify, and redistribute them. The Drupal community is responsible for reviewing and testing contributed components to ensure that they are secure and stable. The community also provides support for contributed components, and can help users troubleshoot any issues they may have.
