 ## What is the Cluster API Provider IBM Cloud
 
-
 The [Cluster API](https://github.com/kubernetes-sigs/cluster-api) brings declarative, Kubernetes-style APIs to cluster creation, configuration and management.
 
 The API itself is shared across multiple cloud providers allowing for true IBM Cloud
 hybrid deployments of Kubernetes.  It is built atop the lessons learned from
 previous cluster managers such as [kops](https://github.com/kubernetes/kops) and
 [kubicorn](http://kubicorn.io/).

+Currently, the CAPIBM project exclusively facilitates the deployment of Kubernetes (K8s) clusters solely on two IBM infrastructure offerings, namely [IBM VPC (Virtual Server Instances)](https://cloud.ibm.com/docs/vpc?topic=vpc-about-advanced-virtual-servers) and [IBM PowerVS](https://cloud.ibm.com/docs/power-iaas?topic=power-iaas-about-virtual-server).
