-Modal Dialog with ActionBar
+The following example is demonstrating how to create a modal page with `ActionBar`. The **_main-view.component_** is the page from which, you will open the root modal (**_modal-root.component_**). The root modal contains a `page-router-outlet` and has a default navigation to **_modal-view.component_** while using the children routing configuration.

-Modal Dialog Navigation
+The following example demonstrates how to enable navigaiton within a modal page. First we have a component which opens the main root modal. The root modal contains a `page-router-outlet` which has a default navigaiton via the `modal` route (loads the **_home-modal-view-content.component_**). The router outlet has its own routing table (**_modal-view-examples.module.ts_**) and can navigate to the `second-modal` route within the root modal.
