+### Nested View Controllers
+
+The SDK sets up a parent-child relationship for nested UIViewControllers, starting with the first UIViewController that your app loads. If there's no active transaction on the scope, the SDK will start a new UIViewController transaction and bind it to the scope unless there's a [user interaction](#user-interaction-tracing) transaction already on the scope, in which case this will be closed and removed first.
+
+While a UIViewController transaction is active on the scope, the SDK will add any new UIViewController spans as child spans of that active transaction. This creates a unified view of all UIViewControllers on a screen in a single transaction.
+
+If another transaction is already bound to the scope (if it's been set manually, for example) the SDK won't be able to bind a new UIViewController transaction to the scope. This means that the new transaction will work, but won’t capture other auto-generated spans, like HTTP, file IO, or Core Data, which can only be added to transactions that are bound to the scope.
