Your site title, tagline and the front page texts.
Here I will show you where to set the wording of your site.
Your site title and tagline live under Settings > General, or visually under Appearance > Customize > Site Identity. The title appears in the header.
The front page texts are all editable under Appearance > Customize > Novelisto Homepage. The next chapters show each section in turn: the hero, the front page sections and the newsletter band.
Every field has a clear label telling you exactly where it appears. Change only what you wish; the rest keep sensible defaults.
