+## Create multiple storage classes
+
+ - create multiple storage classes with different configurations using the `storageClasses` parameter:
+
+```yaml
+storageClasses:
+  - name: smb-csi
+    annotations:
+      storageclass.kubernetes.io/is-default-class: "true"
+    parameters:
+      source: "//smb-server.default.svc.cluster.local/share"
+      # if csi.storage.k8s.io/provisioner-secret is provided, will create a sub directory
+      # with PV name under source
+      csi.storage.k8s.io/provisioner-secret-name: smbcreds
+      csi.storage.k8s.io/provisioner-secret-namespace: default

+      csi.storage.k8s.io/node-stage-secret-namespace: default
+    reclaimPolicy: Delete
+    volumeBindingMode: Immediate
+    allowVolumeExpansion: true
+    mountOptions:
+      - dir_mode=0777
+      - file_mode=0777
+      - noperm
+      - mfsymlinks
+      - cache=strict
+      - noserverino  # required to prevent data corruption
+  - name: smb-csi-retain
+    parameters:
+      source: "//smb-server.default.svc.cluster.local/share"
+      # if csi.storage.k8s.io/provisioner-secret is provided, will create a sub directory
+      # with PV name under source
+      csi.storage.k8s.io/provisioner-secret-name: smbcreds
+      csi.storage.k8s.io/provisioner-secret-namespace: default
+      csi.storage.k8s.io/node-stage-secret-name: smbcreds
+      csi.storage.k8s.io/node-stage-secret-namespace: default
+    reclaimPolicy: Retain
+    volumeBindingMode: Immediate
+    allowVolumeExpansion: true
+    mountOptions:
+      - dir_mode=0777
+      - file_mode=0777
+      - noperm
+      - mfsymlinks
+      - cache=strict
+      - noserverino  # required to prevent data corruption
+```
+
+ - install with custom values:
+```console
+helm install csi-driver-smb csi-driver-smb/csi-driver-smb --namespace kube-system -f custom-values.yaml
+```
+
 ## troubleshooting
 
 - Add `--wait -v=5 --debug` in `helm install` command to get detailed error
