-Note: The second lower button on the badge is used to switch to different messages, currently available only on the iOS app. We plan to implement this function on the Android app in future.
+## What is the other button for?
+
+The **second button** on the LED Badge serves multiple functions:  
+
+- **Message Slot Switching:** This button allows users to **cycle through different pre-stored messages** on the badge. The **app is currently being updated** to fully support this feature, and it will be available in an upcoming release. This will enable users to seamlessly switch between multiple custom messages without needing to reconnect to the app.  
+
+- **Brightness Control:** Holding down the **second button for a longer duration** will allow users to **increase or decrease the brightness of the LEDs**.
