-Step2 - Prepare your Helm values for 4G
-'''''''''''''''''''''''''''''''''''''''
+While you can modify the existing ``values.yaml`` directly, we recommend creating a
+separate values file (e.g., ``myvalues.yaml``) using ``values.yaml`` as a template.
+This approach makes it easier to track your customizations and upgrade in the future.
 
-You can modify existing values.yaml directly, but we recommend composing another value
-file myvalues.yaml using values.yaml as an example. We are highlighting a few things we
-need to modify here. More explanation of the supported Helm values can be found in the
-Configuration section below.
