Hello Guillermo,

Exactly, this is the one you may want to edit. Button is coded in HTML here:

a href=”http://www.fantasticus.nl/sandbox/” class=”btn btn-lg btn-primary”>Agenda

You can easily change Agenda for Home, and when moving your site from sandbox to live domain, you should change the URL to the live one.

I hope that above is useful to you.

Thanks,
Piotr
