+
+[WLED](https://github.com/Aircoookie/WLED) is a fast and feature-rich
+implementation of an ESP8266/ESP32 webserver to control
+NeoPixel (WS2812B, WS2811, SK6812, APA102, and similar) LED's.
+
+## Configuration
+
+This integration can be configured using the integrations in the
+Home Assistant frontend.
+
+Menu: **Configuration** -> **Integrations**.
+
+In most cases, the WLED devices will be automatically discovered by
+Home Assistant. Those automatically discovered WLED devices are listed
+on the integrations page.
+
+If for some reason (e.g., due to lack of mDNS support on your network),
+the WLED device isn't discovered, it can be added manually.
+
+Click on the `+` sign to add an integration and click on **WLED**.
+After completing the configuration flow, the WLED
+integration will be available.
+
+## Lights
+
+This integration adds the WLED device as a light in Home Assistant.
+Home Assistant threats every segment of the LED strip as a separate light
+entity.
+
+Only native supported features of a light in Home Assistant are supported
+(which includes effects).
+
+## Services
+
+This integration currently does not offer any additional services.
