Hi, I want to fork the Rancher origin repo & push the helm chart to my private registry. The problems is

rancher/chart/Chart.yaml

contain some dummy text need to replace with the right version (Ex:

appVersion: %APP_VERSION%

). My question is: 1. How can i replace that value? I find the file

scripts/chart/build

but don't see any document explain what parameter need passing to it. Thank for you support.
