How to edit home page & slider

Hi! I’m new to using third-party themes, and need a little direction to know where I’m going. 🙂 FYI – I’m won’t be having a blog as part of the website, it’s simply a Woocommerce store.

Where do I find the place to edit the Home page? (How do I edit the “about us” and other sections?)

Also, I want to change out the photos on the Home page photo slider. Where can I change out the photos?

Thank you in advance!
