+#### Bot user option
+This plugin supports sending notifications via bot users. You can enable bot user support from both 
+global and project configurations. If the notification will be sent to a user via direct message, 
+default integration sends it via @slackbot, you can use this option if you want to send messages via a bot user.
+You need to provide credentials of the bot user for integration token credentials to use this feature.
