+########################
+
+Overview
+********
+
+The XMC4700 Relax Kit is designed to evaluate the capabilities of the XMC4700
+Microcontroller. It is based on High performance ARM Cortex-M4F which can run
+up to 144MHz.

+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: xmc47_relax_kit
+   :goals: flash
+
+Debugging
+=========
+
+Here is an example for the :ref:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: xmc47_relax_kit
+   :goals: debug
+
+Step through the application in your debugger.
