+## What about IQKeyboardManager?
+If you have [IQKeyboardManager](https://github.com/tjvantoll/nativescript-IQKeyboardManager) installed for better
+keyboard behavior on iOS, then this plugin will detect it and add the height of your custom toolbar to the scroll offset
+IQKeyboardManager applies. You can see this in action in the [NativeScript Core demo app](/demo).
+
+Note that you may want to suppress IQKeyboardManager's own toolbar in this case (to avoid a double toolbar), as shown [here](https://github.com/EddyVerbruggen/nativescript-keyboard-toolbar/blob/f81cfb2e5c84fda16e8e735bf34b1030a8b5eeb6/demo/app/main-view-model.ts#L32-L33).
+
 ## Future work
 - `SearchBar` support.
 - Orientation-change support.
 - Dismiss keyboard on iOS when tapping outside the keyboard (configurable). 
-- Auto-scroll the view if the keyboard overlaps the text field.
-- Modal support on Android (currently you can't use the toolbar in a modal because the toolbar is behind the modal)
