In this sample, routes are configured like this

views.Register(
            new ViewMap<ShellControl, ShellViewModel>(),
            new ViewMap<MainPage, MainViewModel>(),
            new ViewMap<FirstPage, FirstViewModel>(),
            new ViewMap<SecondPage, SecondViewModel>(),
            new ViewMap<ThirdPage, ThirdViewModel>()
            );

        routes
            .Register(
                new RouteMap("", View: views.FindByViewModel<ShellViewModel>(),
                    Nested: new RouteMap[]
                    {
                        new RouteMap("First", View: views.FindByViewModel<FirstViewModel>(), IsDefault: true),
                        new RouteMap("Main", View: views.FindByViewModel<MainViewModel>(),
                            Nested: new RouteMap[]
                            {
                                new RouteMap("Second", View: views.FindByViewModel<SecondViewModel>(), IsDefault: true),
                                new RouteMap("Third", View: views.FindByViewModel<ThirdViewModel>()),
                            }
                        ),
                    }));
