Docs Your site
Your web address
Where your site lives on the web.
Every site gets a Hettie address when you first publish, made from the site's name, like https://my-blog.hettie.dev. Pick the name when you run npx hettie new <name>.
Your own domain
Using your own domain, like example.com, is not ready in the preview yet. Until then, your site lives at its Hettie address.
Changing the site's address in Settings › General only changes the links Hettie writes, like those in the sitemap. It doesn't move the site.
