# Root TabbedPage

A little bit more work is necessary for a `TabbedPage`, and `IPageServiceZero` is here to help!

First we'll need to register our `TabbedPage` in the container. Add the following line to our registrations in `MauiProgram.cs`:

```
.AddSingleton<MultiPage<Page>, AdaptedTabbedPage>()
```

Note we're using an `AdaptedTabbedPage` instead of `TabbedPage`until [this Maui bug](https://github.com/dotnet/maui/issues/14572) is fixed

We'll also need to register the pages and viewmodels the `TabbedPage` is going to present, as well as the mappings from vm to page. See the [Getting Started](/docs/libraries/maui.mvvmzero/walkthrough.md) section for a walkthrough

Once we've registered everything in the container, this is how we configure and launch the app:

```csharp
using FunctionZero.Maui.MvvmZero;
using MvvmZeroTutorial.Mvvm.PageViewModels;

namespace MvvmZeroTutorial
{
    public partial class App : Application
    {
        public App(IPageServiceZero pageService)
        {
            InitializeComponent();
            
            // Don't forget to call pageService.Init, or navigation will not work properly!
            pageService.Init(this);
            
            MainPage = pageService.GetMultiPage(VmInitializer, typeof(ReadyPageVm), typeof(SteadyPageVm), typeof(GoPageVm));
        }

        private bool VmInitializer(object viewModel)
        {
            if (viewModel is ReadyPageVm)
                return false; // Do not wrap the ReadyPage in a NavigationPage.

            return true;
        }
    }
}
```

Simple.
