 The magic happens when the value of the `isSignedIn` variable changes. Let's say, initially `isSignedIn` is `false`. This means, either `SignIn` or `SignUp` screens are shown. After the user signs in, the value of `isSignedIn` will change to `true`. React Navigation will see that the `SignIn` and `SignUp` screens are no longer defined and so it will remove them. Then it'll show the `Home` screen automatically because that's the first screen defined when `isSignedIn` is `true`.
 
-It's important to note that when using such a setup, you **don't need to navigate** to the `Home` screen manually by calling `navigation.navigate('Home')`. React Navigation will automatically navigate to the `Home` screen when `isSignedIn` becomes `true`.
+It's important to note that when using such a setup, you **don't need to manually navigate** to the `Home` screen by calling `navigation.navigate('Home')` or any other method. **React Navigation will automatically navigate to the correct screen** when `isSigned` in changes - `Home` screen when `isSignedIn` becomes `true`, and to `SignIn` screen when `isSignedIn` becomes `false`. You'll get an error if you attempt to navigate manually.
 
-This takes advantage of a new feature in React Navigation: being able to dynamically define and alter the screen definitions of a navigator based on props or state. The example shows stack navigator, but you can use the same approach with any navigator.

 By conditionally defining different screens based on a variable, we can implement auth flow in a simple way that doesn't require additional logic to make sure that the correct screen is shown.
