+- For fixing [#1210 - [BUG]: Helm deployment of PowerFlex driver is failing](https://github.com/dell/csm/issues/1210), a new helm-chart has been released. In order to install this helm chart, we need to pass the flag `--helm-charts-version` during helm installation and flag `-v` during offline bundle installation with value `csi-vxflexos-2.10.1`.

 Alternatively, to do a helm install solely with Helm charts (without shell scripts), refer to `helm/README.md`.
 
  *NOTE:*
+- If you do not specify the `--helm-charts-version` flag, by default the `csi-install.sh` script will clone the version of the helm chart that is specified in the driver's [csi-install.sh](https://github.com/dell/csi-powerflex/blob/main/dell-csi-helm-installer/csi-install.sh#L24) file. If you wish to install the driver using a different version of the helm chart, you need to include this flag. Also, remember to delete the `helm-charts` repository present in the `csi-powerflex` directory if it was cloned before.
 - For detailed instructions on how to run the install scripts, refer to the README.md  in the dell-csi-helm-installer folder.
 - Install script will validate MDM IP(s) in `vxflexos-config` secret and creates a new field consumed by the init container and sdc-monitor container
 - This install script also runs the `verify.sh` script. You will be prompted to enter the credentials for each of the Kubernetes nodes.

 You can upgrade the CSI Driver for Dell PowerFlex using Helm or Dell CSM Operator.
 
-## Update Driver from v2.9.0 to v2.10.0 using Helm
+## Update Driver from v2.9.2 to v2.10.0 using Helm
 **Steps**
 1. Run `git clone -b v2.10.0 https://github.com/dell/csi-powerflex.git` to clone the git repository and get the v2.10.0 driver.
 2. You need to create secret.yaml with the configuration of your system.
 3. Update myvalues file as needed.
 4. Run the `csi-install` script with the option _\-\-upgrade_ by running: 
    ```bash
 
-   cd ../dell-csi-helm-installer && ./csi-install.sh --namespace vxflexos --values ./myvalues.yaml --upgrade
+   cd ../dell-csi-helm-installer && ./csi-install.sh --namespace vxflexos --values ./myvalues.yaml --helm-charts-version csi-vxflexos-2.10.1 --upgrade
    ```
 
 *NOTE:*
+- If you do not specify the `--helm-charts-version` flag, by default the `csi-install.sh` script will clone the version of the helm chart that is specified in the driver's [csi-install.sh](https://github.com/dell/csi-powerflex/blob/main/dell-csi-helm-installer/csi-install.sh#L24) file. If you wish to upgrade the driver using a different version of the helm chart, you need to include this flag. Also, remember to delete the `helm-charts` repository present in the `csi-powerflex` directory if it was cloned before.
 - If you are upgrading from a driver version that was installed using Helm v2, ensure that you install Helm3 before installing the driver.
 - To update any installation parameter after the driver has been installed, change the `myvalues.yaml` file and run the install script with the option _\-\-upgrade_, for example: 
   ```bash
 
-  ./csi-install.sh --namespace vxflexos --values ./myvalues.yaml --upgrade
+  ./csi-install.sh --namespace vxflexos --values ./myvalues.yaml --helm-charts-version csi-vxflexos-2.10.1 --upgrade
   ```
 - The logging configuration from v1.5 will not work in v2.1, since the log configuration parameters are now set in the myvalues.yaml file located at dell-csi-helm-installer/myvalues.yaml. Please set the logging configuration parameters in the myvalues.yaml file.
