 Before RocketMQ deployment, you may need to do some preparation steps for RocketMQ data persistence. 
 
-Currently we provide several options for your RocketMQ data persistence: ```EmptyDir```, ```HostPath``` and ```NFS```, which can be configured in CR files, for example in ```rocketmq_v1alpha1_nameservice_cr.yaml```:
+Currently we provide several options for your RocketMQ data persistence: ```EmptyDir```, ```HostPath``` and ```StorageClass```, which can be configured in CR files, for example in ```rocketmq_v1alpha1_nameservice_cr.yaml```:
 
 ```
 ...
- # storageMode can be EmptyDir, HostPath, NFS
+ # storageMode can be EmptyDir, HostPath, StorageClass
   storageMode: HostPath
 ...
 ```
 
+#### EmptyDir
+
 If you choose ```EmptyDir```, you don't need to do extra preparation steps for data persistence. But the data storage life is the same with the pod's life, if the pod is deleted you may lost the data.
 
 If you choose other storage modes, please refer to the following instructions to prepare the data persistence.
 
-#### Prepare HostPath
+#### HostPath
 
-This storage mode means the RocketMQ data (including all the logs and store files) is stored in each host where the pod lies on. In that case you need to create an dir where you want the RocketMQ data to be stored on. 
-
-We provide a script in ```deploy/storage/hostpath/prepare-host-path.sh```, which you can use to create the ```HostPath``` dir on every worker node of your Kubernetes cluster. 
+This storage mode means the RocketMQ data (including all the logs and store files) is stored in each host where the pod lies on. You need to create a directory on the host where you want the RocketMQ data to be stored. For example:
 
 ```
-$ cd deploy/storage/hostpath
-
-$ sudo su
-
-$ ./prepare-hostpath.sh 
-Changed hostPath /data/rocketmq/nameserver uid to 3000, gid to 3000
-Changed hostPath /data/rocketmq/broker uid to 3000, gid to 3000
+$ mkdir /data/rocketmq/broker
 ```
 
-You may refer to the instructions in the script for more information.
+You can configure the host path in the CRD yaml file like ```hostPath: /data/rocketmq/broker``` in the ```example/rocketmq_v1alpha1_rocketmq_cluster.yaml``` file.
 
-#### Prepare Storage Class of NFS
+#### StorageClass (Use NFS for Example)
 
-If you choose NFS as the storage mode, the first step is to prepare a storage class based on NFS provider to create PV and PVC where the RocketMQ data will be stored. 
+If you choose StorageClass as the storage mode, you need to prepare the storage class related provisioner and other dependencies. Using the NFS storage class as an example, the first step is to prepare a storage class based on NFS provider to create PV and PVC where the RocketMQ data will be stored. 
 
 1. Deploy NFS server and clients on your Kubernetes cluster. You can refer to [NFS deployment document](docs/en/nfs_install_en.md) for more details. Please make sure they are functional before you go to the next step. Here is a instruction on how to verify NFS service.
