+### :date: Release notes addon to Notifications
+There's a function to use a lookup-file to add release note URL's to the notification message.    
+Copy the notify_templates/`urls.list` file to the script directory and modify it as necessary, it will be used automatically if it's there.   
+The output of the notification will look something like this:
+```
+Containers on hostname with updates available:
+apprise-api  ->  https://github.com/linuxserver/docker-apprise-api/releases
+homer  ->  https://github.com/bastienwirtz/homer/releases
+nginx  ->  https://github.com/docker-library/official-images/blob/master/library/nginx
+...
+```
+The `urls.list` file is just an example and I'd gladly see that people contribute back when they add their preferred URLs to their lists.
