How do I set up CKEditor in Drupal?URL Copied
The method by which you set up the editor in Drupal depends on which version of CKEditor you’re using, and the Drupal version where you’re implementing the editor.
When CKEditor is available as a core module, there is no need for installation or any extra steps. When it’s available as a contributed module, you need to install the module yourself. Details about configuration of both core and contributed modules and documentation can be found on the module pages.
