Edition 1.0.0 Add Text to Homepage?

Hi! Is there documentation on the edition 1.0.0 theme release I can refer to? I am interested in adding some text to the home page of my new site (right now it is mocked up as an element of the large image, but I want to place it under the subscription box element) . I am new to GhostPro and trying to find my way around the admin panel. I chose the Starter tier, so if this isn’t available to me because of my selected pricing, please advise. Thanks!
