+[ZigBee Home Automation](http://www.zigbee.org/zigbee-for-developers/applicationstandards/zigbeehomeautomation/)
+integration for Home Assistant allows you to connect many off-the-shelf ZigBee
+devices to Home Assistant, using a compatible ZigBee radio.
+
+There is currently support for the following device types within Home Assistant:
+
+- [Binary Sensor](../binary_sensor.zha) (e.g. motion and door sensors)
+- [Sensor](../sensor.zha) (e.g. temperature sensors)
+- [Light](../light.zha)
+- [Switch](../switch.zha)
+
+Known working ZigBee radios:
+
+- Nortek/GoControl Z-Wave & Zigbee USB Adaptor - Model HUSBZB-1
+
+To configure the component, a `zha` section must be present in the `configuration.yaml`,
+and the path to the serial device for the radio and path to the database which will persist your network data is required.
+
+```yaml
+# Example configuration.yaml entry
+zha:
+  usb_path: /dev/ttyUSB2
+  database_path: zigbee.db
+```
+
+Configuration variables:
+
+ - **usb_path** (*Required*): Path to the serial device for the radio.
+ - **database_path** (*Required*): Path to the database which will keep persisten newtork data.
+
+
+
+To add new devices to the network, call the `permit` service on the `zha` domain, and then follow the device instructions.
