Add a missing part to step 05

@@ -8,5 +8,7 @@ Rough Notes:
 - Decorating the router with UserStateProvider makes UserState available everywhere
 - Write the UserInfo component - the only new feature here is consuming a cascading parameter
 - Add the UserInfo component to the layout so you can see sign-in/sign-out from every page
+- Use the UserStateProvider cascading parameter from Index
+- Add a call to UserStateProvider.TrySignIn on Index when an order is submitted. We don't want to allow unauthenticated orders now
 - Adding a new layout ForceSigninLayout that prevents rendering of content when not signed in
 - Apply this layout to the MyOrders page and OrderDetails page will trigger a signin on navigation
