 # 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

 note, in current implementation, descheduler does not schedule replacement of evicted pods
 but relies on the default scheduler for that.
