- * Plugin definitions like the title of a plugin should be translatable, because
- * the string appears in the UI. Therefore there is an Annotation class, which
- * allows to mark any string as translatable.
+ * When providing plugin annotation, properties whose values are displayed in
+ * the user interface should be made translatable. Much the same as how user
+ * interface text elsewhere is wrapped in t() to make it translatable, in plugin
+ * annotation, wrap translatable strings in the @ Translation() annotation.
+ * For example:
  * @code
  *   title = @Translation("Title of the plugin"),
  * @endcode
- * Additional to the @Translation bit a "use" statement for that class has to be
- * added to the file.
+ * You will also need to make sure that your class file includes the line:
+ * @code
+ *   use Drupal\Core\Annotation\Translation;
+ * @endcode
  * @}
