+### Balance Cluster By Node Memory Utilization
+
+If your cluster has been running for a long period of time, you may find that the resource utilization is not very
+balanced. The `LowNodeUtilization` strategy can be used to rebalance your cluster based on `cpu`, `memory`
+or `number of pods`.
+
+Using the following policy configuration file, descheduler will rebalance the cluster based on memory by evicting pods
+from nodes with memory utilization over 70% to nodes with memory utilization below 20%.
+
+```

 ### Autoheal Node Problems
 Descheduler's `RemovePodsViolatingNodeTaints` strategy can be combined with
