+            Sometimes it is hard to apply Observer to a part of the rendering,
+            for example because you are rendering inside a RenderFragment,
+            and you don't want to extract a new component to be able to mark it as observer.
+            In those cases <Observer /> comes in handy. It takes a child content that
+            is automatically re-rendered if any referenced observables change.
