Somewhere on your site, you should likely want a meeting page.
All text that you see here is running in a Meeting Page, and all of the text that you see is above the map.
Set Up Map
Go to GoogleMaps or an alternative mapping program that provices embed code. Find your location, get the map and make sure it is correct, the select some variant of "share" that will likely say "embed code"
Get the embed code. Then go to the Theme tab and pick Components from the menu on the right.
There is a component for meeting location. Put your embed code there. Save the components.
Edit Your Meeting Page
What follows is an example, and it has the basics -- text above a map. In addition to what has been shown hear, you might want to star a speaker, provide links to supporting documents, etc.
Make sure the Page Options are set to use the meetinglocation.php as the template.
