+The `yeelightsunflower` light platform allows you to control your Yeelight Sunflower light bulbs with Home Assistant.  
+Note that the "Yeelight Sunflower" bulbs are not the same as the "Yeelight WiFi" bulbs. 
+
+### {% linkable_title Example configuration %}
+
+To enable your lights, add the following lines to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+light:
+  - platform: yeelightsunflower
+    host: 192.168.1.59
+```
+
+Configuration variables:
+
+- **host** (*Required*): IP address of your Yeelight Sunflower hub.
+
+<p class='note'>
+When the hub is loaded, your lights will appear as devices with their Zigbee IDs as part of the entity name. 
+</p>
+
+<p class='note warning'>
+The Yeelight Sunflower hub supports SSDP discovery, but that has not been built into the platform. Let the developer know if that would be helpful to you.
