;;; Commentary:
;;
;; This extension extends `org-protocol', adding custom Org-roam handlers to it
;; to provide the next new protocols:
;;
;; 1. "roam-node": This protocol simply opens the node given by the node ID
;; 2. "roam-ref": This protocol creates or opens the node with the given REF
;;
;; You can find detailed instructions on how to setup the protocol in the
;; documentation for Org-roam.
;;

(require 'org-protocol)
(require 'ol) ;; for org-link-decode
(require 'org-roam)
