+	Changes to `scale` will not create a new `deployment`. Annotating after this may result in the message for the previous `deployment` being replaced
+```bash
+# This assumes you've annotated the previous deployment already
+kubectl apply -f deployment.yml
+
+# Annotate the new deployment
+kubectl annotate deployment/myapp-deployment kubernetes.io/change-cause="DESCRIBE_CHANGES_HERE"
+
+# You can then view the rollout history
+kubectl rollout history deployment/myapp-deployment
