• Enable the module in the Administration panel > Modules > User Interface section of your Drupal site.
• Grant permissions for using CKEditor in the Administration panel > People > Permissions section.
• Add your license name and key by editing the Global Profile in the Administration panel > Configuration > Content Authoring > CKEditor > Global settings section. CKEditor will now run in licensed mode.
• Adjust CKEditor profiles in the Administration panel > Configuration > Content Authoring > CKEditor section. Profiles determine which options are available to users based on the input format system.
• If you want to enable CKFinder, an advanced Ajax file browser, see the Installing CKFinder section below.

Installing CKFinder

CKFinder is an Ajax-based file manager created by CKEditor developers: http://ckfinder.com/. It is already included in your licensed CKEditor for Drupal module, so all you need to do is enable it in the Drupal administration panel.

• Grant the "CKFinder access" permission in the Administration panel > People > Permissions section.
• Open the Drupal settings file (sites/default/settings.php) and do the following:
  • Uncomment the $base_url variable and set the base URL of your website (without the trailing slash).
  • Uncomment the $cookie_domain variable and set the domain name of your website.
• Configure CKFinder settings in the File browser settings section for the CKEditor profile that you want to use.
