Content is edited in the admin panel: pages, sections, articles, images. The design comes from ready-made options — there are seven of them, all displayed on the template showcase — you can look them over in advance and pick one. Search-engine markup, the sitemap, and page addresses are all generated automatically by the engine.
The panel has a built-in AI assistant: it helps write text and rework text you've already written, if the wording is giving you trouble.
