+The `yeelight` light platform allows you to control your Yeelight Wifi bulbs with Home Assistant.
+
+To enable those lights, add the following lines to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+  - platform: yeelight
+    devices:
+      192.168.1.25:
+        name: palier
+```
+
+Configuration variables:
+
+- **ip** (*Required*): IP(s) of your wifi bulbs
+- **name** (*Optional*): A friendly name for the device.
+
+<p class='note'>
+Before trying to control your light through Home Assistant, you have to setup your bulb using Yeelight app. ( [Android](https://play.google.com/store/apps/details?id=com.yeelight.cherry&hl=fr), [IOS](https://itunes.apple.com/us/app/yeelight/id977125608?mt=8) ).
+In the bulb property, you have to enable "Developer Mode"
+Determine your bulb ip (using router, software, ping ...)
+</p>
+
+<p class='note warning'>
+Tests are only made with a YLDP03YL model. Because it's the only hardware developer owns. If you have bugs with another kind of model, you could open an issue on [Home Assitant Github](https://github.com/home-assistant/home-assistant)
