 The above example updates cluster autoscaler on the single node pool in *myAKSCluster* to a minimum of *1* and maximum of *5* nodes.
 
+The cluster autoscaler will make its scaling decisions based on the minimum and maximum counts set on each node pool, but it does not enforce them. For example, setting a min-count of 5 when the current node count is 3 will not immediately scale the pool up to 5. If you change the minimum count on the node pool to a value higher than the current number of nodes, this new limit will be respected when there are unschedulable pods present that would require new nodes and trigger an autoscaler event.

 > [!NOTE]
 > You can't set a higher minimum node count than is currently set for the node pool. For example, if you currently have min count set to *1*, you can't update the min count to *3*.
