Oh absolutely! Start by inviting AttendanceBot to a channel by /invite @attendancebot in that channel.
1. To enable announcements for all punches, head to your settings panel by typing 'settings'-->Notifications-->Channel Notifications Settings and click on "Create New"
Now, select the option of "In/Out Notifications" and hit "save changes"
2. To notify people about their team status i.e if they are on break, having lunch, you can similarly set up punch card. You can announce punch card on the channel at a specific time of the day.
Note: Enabling this would make the channel very noisy. Use with caution. You can always come back and disable this.
