+# LED HAL Example
+This example demonstrates and tests the functionality of the LED HAL. You can
+use it to:
+
+* Understand the logic of the LED HAL.
+* Test your implementation of arch-specific LED HAL components if you are
+developing a new port.
+
+This example assumes a device with at least 1 LED.
+
+# Supported devices
+This example is expected to work off-the-shelf on the following boards:
+
+* All CC13xx/CC26xx devices
+* All CC2538 devices
