 ## Pod Priorty
 
-Pods can be assigned priority that reflects the signifance of a pod compared to other pods. For detailed explanation, please refer [https://kubernetes.io/docs/concepts/scheduling-eviction/pod-priority-preemption/](https://kubernetes.io/docs/concepts/scheduling-eviction/pod-priority-preemption/)
+Pods can be assigned priority that reflects the significance of a pod compared to other pods. If a pod cannot be scheduled, the scheduler will attempt to evict lower-priority pods in order to free up resources and allow high-priority pods to be scheduled. Assigning priority to pods is important to make sure high-priority pods are not preempted and get the required resources. It is highly recommended to set a PriorityClass object with the highest possible value for MarkLogic Pods to ensure the availability of the database.
