 # Longhorn
 
-Longhorn is a distributed block storage system built using containers and microservices. Longhorn creates a dedicated storage controller for each block device volume and sychronously replicates the volume across multiple replicas stored on multiple hosts. The storage controller and replicas are implemented using containers and are managed using a container orchestration system.
+Longhorn is a distributed block storage system for Kubernetes. Longhorn is lightweight, reliable, and easy-to-use. You can deploy Longhorn on an existing Kubernetes cluster with one simple command. Once Longhorn is deployed, it adds persistent volume support to the Kubernetes cluster.
 
-Longhorn is lightweight, reliable, and easy-to-use. It is particularly suitable as persistent storage for containers. It supports snapshots, backups, and even allows you to schedule recurring snapshots and backups!
