;;; Commentary:
-;; This add-on displays unread mark ("!") for channels which have
-;; "unread messages".
+;; This add-on marks channels where new messages are arrived.
-;; To use, add the following line to your ~/.riece/init.el:
-;; (add-to-list 'riece-addons 'riece-unread t)
+;; You can check the unread channels via `C-c g' in the commands
+;; buffer, by adding the following lines to ~/.riece/init.el:

+;; (add-hook 'riece-guess-channel-try-functions
