Silly question: do we need to add a link to the faq or the framework will take care of it?

Silly question: do we need to add a link to the faq or the framework will take care of it?

Can we explore the question "adding a link to the FAQ"? Do you mean adding links from other pages to the FAQ page?

BTW, netlify provides the preview of this PR, we can check in https://deploy-preview-448--open-cluster-management.netlify.app/ to see if result match our exception.
