Reviewing in the API documentation, there's a number of smaller issues that should be addressed:

• Top level specification fields have a dot prefix, nested fields don't

https://docs.openshift.com/container-platform/4.5/rest_api/operator_apis/etcd-operator-openshift-io-v1.html#specification

shows .apiVersion but the field name is apiVersion. Sub objects do not.

• about page types should be linked to their individual pages

https://docs.openshift.com/container-platform/4.5/rest_api/operator_apis/operator-apis-index.html#etcd-operator-openshift-iov1 should link to https://docs.openshift.com/container-platform/4.5/rest_api/operator_apis/etcd-operator-openshift-io-v1.html#specification

• type sections in objects should have anchor tags so that other sections can link to them

the spec section on this page https://docs.openshift.com/container-platform/4.5/rest_api/operator_apis/etcd-operator-openshift-io-v1.html#specification should be an anchor link

• spec and status types in top level objects should link to the subsection type

spec here https://docs.openshift.com/container-platform/4.5/rest_api/operator_apis/etcd-operator-openshift-io-v1.html#specification should have the type column link to the anchor tag for the spec object
