 /**
- * Provides entity field instance plugin.
+ * Provides destination plugin for field_config configuration entities.
+ *
+ * The Field API defines two primary data structures, FieldStorage and Field.
+ * A FieldStorage defines a particular type of data that can be attached to
+ * entities as a Field instance.
+ *
+ * The example below adds an instance of 'field_text_example' to 'article'
+ * bundle (node content type). The example uses the EmptySource source plugin
+ * and constant source values for the sake of simplicity. For an example on how
+ * the FieldStorage 'field_text_example' can be migrated, refer to
+ * \Drupal\migrate\Plugin\migrate\destination\EntityFieldStorageConfig.
