+* [Troubleshooting](#Troubleshooting)
+
+## Capabilities
+
+* **Actuator** - represents that a Device has commands
+* **Configuration** - _configure()_ command called when device is installed or device preferences updated
+* **Refresh** - _refresh()_ command for status updates
+* **Power Meter** - ability to check the power meter(energy consumption) of device
+* **Sensor** - represents the device sensor capability
+* **Switch** - can detect state (possible values: on/off)
+* **Switch Level** - represents current light level, usually 0-100 in percent
+* **Health Check** - indicates ability to get device health notifications
+
+## Device Health
+
+A Zigbee dimmer with maxReportTime of 5 mins.
+Check-in interval is double the value of maxReportTime.
+This gives the device twice the amount of time to respond before it is marked as offline.
+Enrolls with default periodic reporting until newer 5 min interval is confirmed
+It then enrolls the device with updated checkInterval i.e. 12 mins
+
+## Troubleshooting
+
+If the device doesn't pair when trying from the SmartThings mobile app, it is possible that the device is out of range.
+Pairing needs to be tried again by placing the device closer to the hub.
+Instructions related to pairing, resetting and removing the device from SmartThings can be found in the following link:
