+      # Descheduler for Kubernetes
+
+      ## Introduction
+
+      Scheduling in Kubernetes is the process of binding pending pods to nodes, and is performed by
+      a component of Kubernetes called kube-scheduler. The scheduler's decisions, whether or where a
+      pod can or can not be scheduled, are guided by its configurable policy which comprises of set of
+      rules, called predicates and priorities. The scheduler's decisions are influenced by its view of
+      a Kubernetes cluster at that point of time when a new pod appears first time for scheduling.
+      As Kubernetes clusters are very dynamic and their state change over time, there may be desired
+      to move already running pods to some other nodes for various reasons
+
+      * Some nodes are under or over utilized.
+      * The original scheduling decision does not hold true any more, as taints or labels are added to
+      or removed from nodes, pod/node affinity requirements are not satisfied any more.
+      * Some nodes failed and their pods moved to other nodes.
+       New nodes are added to clusters.
+
+      Consequently, there might be several pods scheduled on less desired nodes in a cluster.
+      Descheduler, based on its policy, finds pods that can be moved and evicts them. Please
+      note, in current implementation, descheduler does not schedule replacement of evicted pods
+      but relies on the default scheduler for that.
+
+      ## Note
+
+      Any api could be changed any time with out any notice. That said, your feedback is
+      very important and appreciated to make this project more stable and useful.
