The location listed on your website is powered by two sections in your admin:
Contact Information
This section controls the address that appears in your footer and your email signature.
Locations
This section controls the address(es) that appear on your "Contact" page.
For each location that you add to this section, the following information can be added to the "Contact" page on your website:
Address
Phone number
Fax number
Hours
Google map (automatically generated)
If more than one location is added, you'll have the option to set one as the "primary" location. The primary location will appear at the top of your "Contact" page.
