Drupal is a content management system (CMS) that helps you create and manage digital content. Drupal is open source software released under the GNU General Public License, meaning that it’s free to use and modify. It also means that there are a lot of people who can help you with troubleshooting or developing new features.

Drupal works by allowing you to create “modules” which add specific functionality to your site. There are thousands of modules available, so you can find one for just about anything you want to do. You can also create your own modules if needed.

One of the great things about Drupal is that it’s very scalable. It can be used for small sites or large ones with millions of pages. Drupal is also very secure, and has been used by organizations like the White House, Harvard University, and The Guardian.

If you’re looking for a powerful, versatile, and secure CMS, Drupal is a great option.
