How do I change the name and/or date on the home/cover page?
Under Edit Content, click Home. You'll then a few fields, but the two you'll want to use are:
Title (this is where you can add your names or whatever text you would prefer to show up in that spot)
Sub-title (this is where you can add your wedding date or whatever text you would prefer to show up in that spot)
The text that you'll see already in those text fields is just placeholder text that is there to serve as an example. Just click inside the box and you can edit it.
