 #### Reloading
 
-The provisioner supports automatic configuration reloading. Users can change the configuration using `kubectl apply` or `kubectl edit` with config map `local-path-config`. There is a delay between when the user updates the config map and the provisioner picking it up.
+The provisioner supports automatic configuration reloading. Users can change the configuration using `kubectl apply` or `kubectl edit` with config map `local-path-config`. There is a delay between when the user updates the config map and the provisioner picking it up. In order for this to occur for updates made to the helper pod manifest, the following environment variable must be added to the provisioner container. If not, then the manifest used for the helper pod will be the same as what was in the config map when the provisioner was last restarted/deployed.
+
+```yaml
+- name: CONFIG_MOUNT_PATH
+  value: /etc/config/
+```
 
 When the provisioner detects the configuration changes, it will try to load the new configuration. Users can observe it in the log
