How to change what feeds to "Learn more about" section on Customer Portal

[Krista Gracie]

Today, I turned on the Confluence Knowledge Base for my Service Desk project. 

On the customer portal (configured in Jira), there is a new section that is linked to the knowledge base with the header "Learn more about". 

• Can I change/ replace the words "Learn more about"? 
• What causes things to show up in this section? Is that something I can configure/organize a different way to be more accurate? 

Also, if anyone who sees this has good resources on configuring or organizing the knowledge base, great examples, or tips... I'm open to ideas.
