 ### Mount an NFS share using /etc/fstab
 
-If you want the NFS file share to automatically mount every time the Linux server or VM boots, create a record in the **/etc/fstab** file for your Azure file share. Replace `YourStorageAccountName` and `FileShareName` with your information.
+If you want the NFS file share to automatically mount every time the Linux server or VM boots, create a record in the **/etc/fstab** file for your Azure file share. The record will differ depending on whether or not you're using the AZNFS Mount Helper or the native NFS mount commands.
+
+To determine whether the AZNFS Mount Helper package is installed on your client, run the following command:
+
+```bash
+systemctl is-active --quiet aznfswatchdog && echo -e "\nAZNFS Mount Helper is installed! \n"
+```
+
+If the package is installed, then the message `AZNFS Mount Helper is installed!` appears.
+
+The record in **/etc/fstab** should look like this if you're using the AZNFS Mount Helper and want to mount the share using encryption in transit:
+
+```bash
+<YourStorageAccountName>.file.core.windows.net:/<YourStorageAccountName>/<FileShareName> /media/<YourStorageAccountName>/<FileShareName> aznfs defaults,sec=sys,vers=4.1,nolock,proto=tcp,nofail,_netdev   0 2
+```
+
+If you're using the AZNFS Mount Helper but don't want to use encryption in transit, the record in **/etc/fstab** should look like this:
+
+```bash
+<YourStorageAccountName>.file.core.windows.net:/<YourStorageAccountName>/<FileShareName> /media/<YourStorageAccountName>/<FileShareName> aznfs defaults,sec=sys,vers=4.1,nolock,proto=tcp,nofail,_netdev,notls   0 2
+```
+
+If you're using the native NFS mount without AZNFS, the record in **/etc/fstab** should look like this:
 
 ```bash
 <YourStorageAccountName>.file.core.windows.net:/<YourStorageAccountName>/<FileShareName> /media/<YourStorageAccountName>/<FileShareName> nfs vers=4,minorversion=1,_netdev,nofail,sec=sys 0 0
 ```
 
-For more information, enter the command `man fstab` from the Linux command line.
