 ## What is S2I/B2I
 
-Kubesphere S2I(Source-to-Image) / B2I(Binary-to-Image) provides easy CI/CD functionalities, help developers to publish their service to Kubernetes without writing Dockefile.
+KubeSphere S2I (Source-to-Image) / B2I (Binary-to-Image) provides easy-to-use CI/CD functionalities, helping developers to publish their services to Kubernetes without writing Dockefile.

 ## Principle
 
-All resources of S2I/B2I will be installed in namespace `kubesphere-devops-system` by enable devops component.
+All resources of S2I/B2I will be installed in namespace `kubesphere-devops-system` when DevOps component enabled.
 
-In S2I, all resources and CI/CD steps are defined with [Custom Resource Defintion](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/) (CRD). You can operate all s2i resources by call k8s api directly.

+There are two modules included in the S2I component:
 
-1. S2I Operator: A Kubernetes CRD controller that provides easy Kubernetes-style resources for declaring CI/CD-style pipelines
-2. S2IRun: It is the instance that executes the s2i build process in containers.
