+This strategy evicts pods that are older than `maxPodLifeTimeSeconds`. The policy file should look like:
 
-````
+```
 apiVersion: "descheduler/v1alpha1"
 kind: "DeschedulerPolicy"
 strategies:
   "PodLifeTime":
      enabled: true
      params:

+
+You can specify `podStatusPhases` to `only` evict pods with specific `StatusPhases`, currently this parameter is limited
+to `Running` and `Pending`. E.g.
+
+```
+apiVersion: "descheduler/v1alpha1"
+kind: "DeschedulerPolicy"
+strategies:
+  "PodLifeTime":
+     enabled: true
+     params:
+       podLifeTime:
+         maxPodLifeTimeSeconds: 86400
+         podStatusPhases:
+         - "Pending"
+```
+
+Only `Pending` pods will get evicted in this example.
