+* `minAvailable` which is a description of the number of pods from that
 set that must still be available after the eviction, i.e. even in the absence
 of the evicted pod. `minAvailable` can be either an absolute number or a percentage.

+You can specify only one of `maxUnavailable` and `minAvailable` in a single `PodDisruptionBudget`. 
+`maxUnavailable` can only be used to control the eviction of pods

+is the `scale` of the controller managing the pods being selected by the
+`PodDisruptionBudget`.
+
+Example 1: With a `minAvailable` of 5, evictions will be allowed as long as they leave behind
+5 or more healthy pods among those selected by the PodDisruptionBudget's `selector`.
+
+Example 2: With a `minAvailable` of 30%, evictions will be allowed as long as at least 30%
+of the number of desired replicas are healthy. 
+
+Example 3: With a `maxUnavailable` of 5, evictions will be allowed as long as there are at most 5
+unhealthy replicas among the total number of desired replicas.
+
+Example 4: With a `maxUnavailable` of 30%, evictions will be allowed as long as no more than 30% 
+of the desired replicas are unhealthy.

+In typical usage, a single budget would be used for a collection of pods managed by

 ## Requesting an eviction
 
+See the task explaining [draining nodes](/docs/tasks/administer-cluster/safely-drain-node/) for a higher level construct used to trigger evictions of pods on chosen nodes.

 If you are writing infrastructure software that wants to produce these voluntary
 evictions, you will need to use the eviction API.  The eviction subresource of a
 pod can be thought of as a kind of policy-controlled DELETE operation on the pod
