How to enable Homepage Control section

Hi great theme,

In the customizer there’s a tab for Homepage Control, it displays:

No homepage components found. Please contact your theme author to make your theme compatible with Homepage Control or see this guide for details on how to do it yourself.

Should I use homepage control plugin or which solution.

I’d lose any code edits if I used this approach:

Should I create a child-theme or what?

Thanks
