+# utils
+
+Some simple scripts that can ease the use of chatdir clients.
+
+## chatdir-in.sh
+Messages are sent, in chatdir, via .in/ directories under each channel's dir.
+The file can be named whatever, it just has to be a text-file, and it'll be
+sent. But `$ echo "Hi there!" > #general/.in/msg` is annoying.
+
+This is a wrapper around that. It will send whatever you type to the selected
+channel; selecting a channel is done by just typing a channel name verbatim.
+There is auto-completion for both nicks and channel-names.
+
+You might run it like, `$ chatdir-in.sh ~/chat/libera.chat/`
+
+
+## irc_file_notify.sh
+Sends a pretty notification (with icon, sender, and message text!) whenever a
+message is sent. You might run like, `$ irc_file_notify.sh ~/chat/libera.chat/*`
+
+
+## proc_notify.sh
+Displays a warning notifcation when irc-chatdir dies.
+You might run like, `$ proc_notify.sh irc-chatd.scm.*leagueh`
