Open Settings in your site's menu.
- Business name: shown in your site's header and footer, in its copyright line and in the browser tab.
- Phone number and email: they replace the template's sample ones on every page, in the words and in the buttons that call or write to you.
- Address: it replaces the template's sample street wherever the template shows one.
- Opening hours: kept with your details, one line.
The templates come with sample contact details so you can see the design. A published site never shows them: until you add your own phone number or email, none appears at all.
Settings is also where you delete a site you no longer need. That cannot be undone.
