you can only edit levels you submitted yourself (or, if you're an admin, anyone's).
the page content field is freeform — structure it however you like, with
**bold**, *italic*, > quotes, headings, images, whatever the
page needs. the toolbar inserts markdown for you, or write HTML tags like
<h1> and <img> directly. images can have a caption:
. the tabs button inserts a tabbed section
([tabs][tab Name]...[/tab][/tabs]) for variant content like the real wiki's
Arches/Pillars tabs. the diagram-icon button searches every level and entity — curated and
community — and inserts a link to whichever one you pick. the upload button lets you pick an
image file straight from your device instead of hosting it elsewhere and pasting a URL.
