+## VIP of the Month
+
+In this example a channel-point reward for one month of VIP status exists which is automated through the bot. To get the `.reward_id` you can use the [Debug-Overlay]({{< ref "../overlays/_index.md" >}}) or just use the `.reward_title` variable and check against the name of the reward.
