 **Note**: You may wish to disable one of the notifications if another service (ex:
 Honeybadger) also displays a deploy notification.
 
 Test your setup by running:
 
     $ cap production slack:deploy:starting
     $ cap production slack:deploy:finished
+    $ cap production slack:deploy:failed
 
 ## Usage
 
 Deploy your application like normal and you should see messages in the channel
 you specified.
