A Drupal distribution is an all-inclusive package to get your website up and running quickly. This package consists of the Drupal Core (basic features), installation profiles, themes (for customized designs), libraries (consists of assets like CSS or Javascript) and modules specific to an industry. For example, if you run a publishing company, a distribution like Thunder can help you speed up your development process. Here you can find modules like Paragraphs, Media Entity, Entity Browser and features like Thunder admin theme, scheduled publishing and much more – all in one place.
