+** Roam

+   As stated in [[info:org-roam#Getting Started][the manual]], org-roam needs to know where notes are
+   stored. I'm going to go with =~/org/zet=, as its nice having all
+   org documents under =~/org=, but also we need to distinguish
+   zettels from other org stuff.

+     (setq org-roam-directory "~/org/zet")
+   #+end_src
+
+   And, also as recommended, we'll start [[help:org-roam-mode][org-roam-mode]] after init:
+
+   #+begin_src emacs-lisp
+     (add-hook 'after-init-hook 'org-roam-mode)
