Apple Notes can import a markdown file and format it for you. So instead of a PDF telling you how to build a wiki, this is the wiki itself.

One file. Import it and you get a Home note with five sections, a starter tag list, and the four moves that run the system, all already formatted.

Inside: a pre-built Home note with link slots, nine starter tags, note links and section links and tables of contents and dividers each explained in under a minute, a fifteen-minute setup path in order, and an honest list of what Apple Notes still cannot do.

Works on iOS 26 and later. On iOS 27 you can skip the import and paste it straight in.
