+Signals and Animation Node Observers
+------------------------------------
+
+Certain animation node types support an :ref:`AnimationNodeObserver <class_AnimationNodeObserver>` parameter which relays animation events through signals.
+For example, :ref:`AnimationNodeTransition <class_AnimationNodeTransition>` can be configured with an :ref:`AnimationNodeObserverTransition <class_AnimationNodeObserverTransition>`
+which emits signals when a transition state starts and finishes:
