-Conversely, changes can be applied to `OuterList` and `InnerList` with adapted methods around list handling:
+To Create `OuterList` and `InnerList` instances you can use the `fromMembers` name constructor:

+```php

+use Bakame\Http\StructuredFields\Item;

+```php

 ### Item and RFC Data Types
 
 To handle an item, the package provide a specific `Item` value object with additional named constructors.
