+# RGB LED Example
+This example demonstrates and tests the functionality of the RGB LED driver.
+You can use it to:
+
+* Understand the logic of the RGB LED driver.
+* Test your implementation if you are developing a new port for a device that
+features this part.
+
+This example assumes a device with an RGB LED.
+
+# Supported devices
+This example is expected to work off-the-shelf on the following boards:
+
+* All Zoul-based devices
