Drupal is an open source content management platform supporting a variety of websites ranging from personal weblogs to large community-driven websites. For more information, visit the Drupal website, Drupal.org, and join the Drupal community.
Contributing
Drupal is developed on Drupal.org, the home of the international Drupal community since 2001!
Drupal.org hosts Drupal's GitLab repository, its issue queue, and its documentation. Before you start working on code, be sure to search the issue queue and create an issue if your aren't able to find an existing issue.
Every issue on Drupal.org automatically creates a new community-accessible fork that you can contribute to. Learn more about the code contribution process on the Issue forks & merge requests page.
Usage
For a brief introduction, see USAGE.txt. You can also find guides, API references, and more by visiting Drupal's documentation page.
You can quickly extend Drupal's core feature set by installing any of its thousands of free and open source modules. With Drupal and its module ecosystem, you can often build most or all of what your project needs before writing a single line of code.
Changelog
Drupal keeps detailed change records. You can search Drupal's changes for a record of every notable breaking change and new feature since 2011.
