There is not clear guide about creating install-config.yaml when using oc-mirror.

Before oc-mirror method released, RH guided customer to use 'oc adm relase mirror' command. When 'oc adm relase mirror' is used, the 'imageContentSources:' was out like below at the end of the mirror process.
~~~
imageContentSources: 
- mirrors:
  - <local_registry>/<local_repository_name>/release
  source: quay.io/openshift-release-dev/ocp-release
- mirrors:
  - <local_registry>/<local_repository_name>/release
  source: quay.io/openshift-release-dev/ocp-v4.0-art-dev 
~~~

However, when customers are using oc-mirror, there is not output printed about 'imageContentSources:'. There is only the results-*/imageContentSourcePolicy.yaml file. Customers don't know what to put in the 'imageContentSources:' part of install-config.ymal[1].

Before, when I was using 'oc adm release mirror' command, I could see ' 'imageContentSources:' when the mirror process was completed. On the contrary, when I'm using oc-mrirror there is no 'imageContentSources:' printed. I know there is output called imageContentSourcePolicy.yaml but this is to be used after installation.

Please make 'imageContentSources:' printed at the end of the mirror process so I can copy and paste for install-config.yaml.
Or, Please revise the official document about install-config.yaml part to guide where I can find the 'imageContentSources:' when using oc-mirror.
