# Create your ViewModels
First we're going to create a couple of base classes for our PageViewModels and ViewModels. It's not necessary, but it makes life much easier if we later on want to insert our own base class functionality. If you do not wish to do this then you can simply derive your `ViewModel` classes directly from the library implementations (or not - `MvvmZero` does not require you use its base classes)
In your `Mvvm/PageViewModels` folder, add the following `abstract` class:
```csharp
using FunctionZero.Maui.MvvmZero;
namespace MvvmZeroTutorial.Mvvm.PageViewModels
{
public abstract class BasePageVm : MvvmZeroBasePageVm
{
}
}
```
Similarly, in your `Mvvm/ViewModels` folder, add the following `abstract` class:
```csharp
using FunctionZero.Maui.MvvmZero;
namespace MvvmZeroTutorial.Mvvm.ViewModels
{
public abstract class BaseVm : MvvmZeroBaseVm
{
}
}
```
Now we want to create a `ViewModel` for each of the `ContentPages`. In the `Mvvm/PageViewModels` folder, add `ReadyPageVm`
Adding our first ViewModel
Make the class `public` and derive from our base implementation for a `PageViewModel`:
```csharp
namespace MvvmZeroTutorial.Mvvm.PageViewModels
{
public class ReadyPageVm : BasePageVm
{
}
}
```
Repeat the process for `SteadyPageVm`, `GoPageVm` and `DetailPageVm`
And here we are:
4 ViewModels added to the project
Next we're going to register our `Pages` and `ViewModels` so they can be presented.
