Per our recent conversation the general direction here looks good @rolfedh

So yeah, as the next step (separate PR per our discussion) we would like to see "Configure Jenkins images" from https://deploy-preview-43039--osdocs.netlify.app/openshift-enterprise/latest/openshift_images/using_images/images-other-jenkins.html move under CI/CD -> Jenkins, BEFORE the migrating article.

And similarly "Jenkins agent" https://deploy-preview-43039--osdocs.netlify.app/openshift-enterprise/latest/openshift_images/using_images/images-other-jenkins-agent.html would slot in after "Configuring.." but before "Migrating..."

Then "Images -> Using Images" would become "Images -> Using Source-to-image" with the remaining 3 articles that are source to image centric (their titles might need some tweaking").
