 #### 1. create a pod with csi azurefile driver mount on linux
 ##### Option#1: Azurefile Dynamic Provisioning
  - Create an azurefile CSI storage class
-```
+```console
 kubectl create -f https://raw.githubusercontent.com/kubernetes-sigs/azurefile-csi-driver/master/deploy/example/storageclass-azurefile-csi.yaml
 ```
 
  - Create an azurefile CSI PVC
-```
+```console
 kubectl create -f https://raw.githubusercontent.com/kubernetes-sigs/azurefile-csi-driver/master/deploy/example/pvc-azurefile-csi.yaml
 ```
 
 ##### Option#2: Azurefile Static Provisioning(use an existing azure file share)
  - Use `kubectl create secret` to create `azure-secret` with existing storage account name and key
-```
+```console
 kubectl create secret generic azure-secret --from-literal accountname=NAME --from-literal accountkey="KEY" --type=Opaque
 ```
 
  - Create an azurefile CSI PV, download `pv-azurefile-csi.yaml` file and edit `shareName` in `volumeAttributes`
-```
+```console
 wget https://raw.githubusercontent.com/kubernetes-sigs/azurefile-csi-driver/master/deploy/example/pv-azurefile-csi.yaml
 vi pv-azurefile-csi.yaml
 kubectl create -f pv-azurefile-csi.yaml
 ```
 
  - Create an azurefile CSI PVC which would be bound to the above PV
-```
+```console
 kubectl create -f https://raw.githubusercontent.com/kubernetes-sigs/azurefile-csi-driver/master/deploy/example/pvc-azurefile-csi-static.yaml
 ```
 
 #### 2. validate PVC status and create an nginx pod
  - make sure pvc is created and in `Bound` status finally
-```
+```console
 watch kubectl describe pvc pvc-azurefile
 ```
 
  - create a pod with azurefile CSI PVC
-```
+```console
 kubectl create -f https://raw.githubusercontent.com/kubernetes-sigs/azurefile-csi-driver/master/deploy/example/nginx-pod-azurefile.yaml
 ```
 
 #### 3. enter the pod container to do validation
  - watch the status of pod until its Status changed from `Pending` to `Running` and then enter the pod container
-```
+```console
 $ watch kubectl describe po nginx-azurefile
 $ kubectl exec -it nginx-azurefile -- bash
 root@nginx-azurefile:/# df -h
