 We have provided high level Swift controller and a UIkit view to easily add Rive into your application. All of 
 this is built ontop of an objective c layer that allows for fine grained granular animation control.
 
+## SwiftUI
+
+In both SwiftUI and UIKit/Storyboard usage, you import the `RiveRuntime` into your appropriate files and interface with the `RiveViewModel` to instantiate and control Rive files.
+
+### RiveViewModel
+The simplest way of adding Rive to a View is the following:
+
+```swift
+struct SwiftSimpleAnimation: DismissableView {
+    var dismiss: () -> Void = {}
+
+    var body: some View {
+        RiveViewModel(fileName: "truck").view()
+    }
+}
+```
+
+Don't forget to call the `.view()` method in the View body! See additional usage below for more configuration options.

-### Mixing
-Mixing goes further than just playing multiple animations at the same time, animations can use 
-a mix factor between 0 and 1, to allow multiple animations effects to blend together. The high

-libraries. The advance function is where you can specify a mix factor.
