 ```js
 Navigation.events().onAppLaunched(() => {
   Navigation.setRoot({
-    container: {
+    component: {
       name: 'navigation.playground.WelcomeScreen'
     }

-### registerContainer(screenID, generator)
+### registerComponent(screenID, generator)
 Every screen component in your app must be registered with a unique name. The component itself is a traditional React component extending React.Component.
 
 ```js
-Navigation.registerContainer(`navigation.playground.WelcomeScreen`, () => WelcomeScreen);
+Navigation.registerComponent(`navigation.playground.WelcomeScreen`, () => WelcomeScreen);
 ```
 
 ### setRoot({params})
 
 ```js
 Navigation.setRoot({
-  container: {
