 ### **Installing on Kubernetes**
 
-When you install KubeSphere on Kubernetes, you need to download the file [cluster-configuration.yaml](https://github.com/kubesphere/ks-installer/releases/download/v3.0.0/cluster-configuration.yaml) for cluster setting. If you want to install App Store, do not use `kubectl apply -f` directly for this file.
+The process of installing KubeSphere on Kubernetes is same as stated in the tutorial of [Installing KubeSphere on Kubernetes](../../installing-on-kubernetes/introduction/overview/) except the optional component App Store needs to be enabled first in the [cluster-configuration.yaml](https://github.com/kubesphere/ks-installer/releases/download/v3.0.0/cluster-configuration.yaml).

In the tutorial of [Installing KubeSphere on Kubernetes](../../installing-on-kubernetes/introduction/overview/), you execute `kubectl apply -f` first for the file [kubesphere-installer.yaml](https://github.com/kubesphere/ks-installer/releases/download/v3.0.0/kubesphere-installer.yaml). After that, to enable App Store, create a local file cluster-configuration.yaml.
+1. Download the file [cluster-configuration.yaml](https://github.com/kubesphere/ks-installer/releases/download/v3.0.0/cluster-configuration.yaml) and open it for editing.
