-## Customized Routing
-
-You can also route messages to different channels on a per-project basis. To
-do this, create a project custom field (Administration > Custom fields > Project)
-named `Messenger Channel`. If no custom channel is defined for a project, the parent
-project will be checked (or the default will be used). To prevent all notifications
-from being sent for a project, set the custom channel to `-`.
-
-For more information, see [https://www.redmine.org/projects/redmine/wiki/Plugins](https://www.redmine.org/projects/redmine/wiki/Plugins) (see also next section for an easy configuration demonstration).
