+### Using plain UIViews instead of view controllers
+
+Since version 1.3.x ScrollStack can also be used to layout plain `UIView` instances which not belong to a parent view controllers.  
+This is especially useful when you don't have a complex logic in your views and you want to use ScrollStack to make custom layout and keep your code lightweight.
+
+Using plain views is pretty easy; each row method supports both `UIView` or `UIViewController` as parameter.
+
+Since you are working with plain `UIView` instances in order to size it correctly you must set its `heightAnchor` or `widthAncor` (depending of your stack orientation) before adding it to the stack.
+As for controllers, `ScrollStack` keeps a strong reference to the managed view which is added as `contentView` of the parent `ScrollStackRow` instance as it happens for `UIViewController`'s `.view` property.
+
+This is a small example:
+
+```swift
+let myCustomView = UIView(frame: .zero)
+myCustomView.backgroundColor = .green
+myCustomView.heightAnchor.constraint(equalToConstant: 300).isActive = true
+stackView.addRow(view: myCustomView)
+```
