Org-roam is a knowledge management system, or personal wiki, built on top of Emacs’ Org-mode. It implements a networked thought system, similar to Roam Research, allowing users to create interconnected notes in a non-hierarchical way. This facilitates effortless linking and discovery of connections between ideas, effectively creating a “second brain” for managing information. Setting up Org-roam Since I’m also publishing the notes using hugo, some properties are needed.
