Fun fact: you can build out content on your Front Page using the Block Editor tool! You may already have some content built out for you already. If you have content on your Front Page that has been created in the Block Editor, there are two ways to know if this is true for you:
1) Check Publish>Pages for a page called, “Front Page"
2) If you’re logged in the platform and you go to your Front Page, you should see a small “Edit” button above the content), and you want to edit that content without taking the changes live on your Front Page, just make a copy of that page under Publish>Pages, play around with the content, and then copy and paste the changes over to your actual Front Page.
