+
+Please note that the old [/deep/ layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/classes)
+are deprecated, and should not be used. To continue using layout properties

+[layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/iron-flex-layout-classes.html).
+Please note that the new version does not use `/deep/`, and therefore requires you
+to import the `dom-modules` in every element that needs to use them.
 
 A complete [guide](https://elements.polymer-project.org/guides/flex-layout) to `<iron-flex-layout>` is available.
