+# ST B-L072Z-LRWAN1 - PlatformIO - Double-Tap Example
+
+This example demonstrates using the motion sensor data on the X-NUCLEO-IKS01A3 expansion shield from a PlatformIO development environment. For more information on adding your device to the Helium network, visit our quickstart guide [here](https://developer.helium.com/console/quickstart). For more information on setting up your PlatformIO IDE, visit our guide [here](https://developer.helium.com/resources/getting-started-with-platformio).
