UPDATE: There is nothing wrong with this guide, and a lot that is good. But the main purpose of it, to use ordinary org mode structure rather than a single-file-per-node model, is now supported by org-roam, and you may use that.
This is a tutorial for a Zettelkasten system based on pure Org mode. It is based on the excellent Zetteldeft tutorial. I have rewritten a lot, but the original concepts and a lot of the original text are from the guide to Zetteldeft.
Clone this repository and open file START HERE.org in Emacs to get started. Or, read online.
