The oc command (oc new-app -f openshift/che-plugin-registry.yml assumes the user knows where to find the openshift directory within the repository (it's not a top-level) directory.

The doc should point users to:

Upstream:

• deploy/openshift
• deploy/openshift

Downstream:

• dependencies/che-plugin-registry/openshift
• dependencies/che-devfile-registry/openshift – this dir doesn't exist right now; see CRW-1293
