+# Removes all finalizers from the selected resource. Finalizers are namespaced keys that tell Kubernetes to wait
+# until specific conditions are met before it fully deletes resources marked for deletion.
+# Before deleting an object you need to ensure that all finalizers has been removed. Usually this would be done
+# by the specific controller but under some circumstances it is possible to encounter a set of objects blocked
+# for deletion.
+# This plugins makes this task easier by providing a shortcut to directly removing them all.
+# Be careful when using this plugin as it may leave dangling resources or instantly deleting resources that were
+# blocked by the finalizers.
