 If you have worked with Ionic Framework before, this should feel familiar. We create an `IonTabs` component and provide an `IonTabBar`. The `IonTabBar` provides `IonTabButton` components, each with a `tab` property that is associated with its corresponding tab in the router config. We also provide an `IonRouterOutlet` to give `IonTabs` an outlet to render the different tab views in.
 
+:::tip
+`IonTabs` renders an `IonPage` for you, so you do not need to add `IonPage` manually here.

 ### How Tabs in Ionic Work
 
 Each tab in Ionic is treated as an individual navigation stack. This means if you have three tabs in your application, each tab has its own navigation stack. Within each stack you can navigate forwards (push a view) and backwards (pop a view).
