google verification code

I’m getting ready to publish my new “Responsive” themed website. I want to use the Webmaster Tools Google Site Verification field. My question is what is the proper format for the entry. The Google instructions were for: “googleanaaannnnnnnnnnn.html”. What portion of that do I enter? I’m pretty sure I leave the .html off, but what about the “google” at the front?

Thx Ken
