-### Common dca fields
-
-The bundle provides some common dca fields that can be used in your dca files.
-
-#### Author field
-
-Add an author field to your dca. It will be initialized with the current backend user. On copy, it will be set to the current user.
-
-```php
-# contao/dca/tl_example.php
-use HeimrichHannot\UtilsBundle\Dca\AuthorField;
-
-AuthorField::register('tl_example');
-```
-
-You can pass additional options to adjust the field:
-
-```php
-# contao/dca/tl_example.php
-use HeimrichHannot\UtilsBundle\Dca\AuthorField;
-
-AuthorField::register('tl_example', [
-    'type' => AuthorField::TYPE_USER, // can be change to TYPE_MEMBER to set a frontend member instead of a backend user
-    'fieldNamePrefix' => '', // custom prefix for the field name
-    'useDefaultLabel' => true, // set to false to disable the default label and set a custom label in your dca translations
-    'exclude' => true, 
-    'search' => true,
-    'filter' => true,
-]);
-```
