 # Curve-Operator
 
 ## What's curve-operator
 
-The curve-operator project helps deploy a Curve cluster orchestrated by Kubernetes.(Currently only supports CurveBS cluster deployment)
+curve-operator manages [Curve](https://github.com/opencurve/curve) cluster on [Kuberentes](https://kubernetes.io/docs/home/). It make Curve a truly cloud-native distributed storage system.
