Kubeflow installation on openshift

I am having problems in installing kubeflow v1.8 on openshift 4.12.13, there are no proper docs. there is no proper installation docs to follow, and it is frustrating. It will work if i can install any lower version of kubeflow on openshift v4.12.13, but something should get installed atleast.
I am having same problem as this gentelman: Issue with installing kubeflow on Openshift CodeReady Container · Issue #7096 · kubeflow/kubeflow · GitHub
