Make Logo at Top, a link to home page

[MarkSmith]

I posed the question as to how I make the logo at the top of my page, a link back to the home page.  Here is the response: Just change url inside your public_html/storefront/view/default/template/common/header.tpl
You can do this manually via hardcode or via some hook. First way easier.

I am a NOT a programmer or even savvy on this.  How is this done??
Thanks
