+/*
+ * DESCRIPTION
+ * This code updated sensor data on the Nimbelink ST Development Kit (NL-AB-ST-NCL) and sends
+ * the information to www.dweet.io using the Thingname "DeviceID". That information can be
+ * viewed using a Freeboard at www.freeboard.io (account required). Depending on your
+ * ST Development Kit version, clone the following freeboard:
+ * Rev A (Legacy): https://freeboard.io/board/jqlneI
+ * Rev B (Current): https://freeboard.io/board/LhnbrX
+ *
+ * Please consult the wiki for more information
+ */
+
+/*
+ * INSTRUCTIONS FOR USING THIS CODE
+ * 1. Under the "DEFINE THE SKYWIRE MODEM" section of the code, uncomment the modem that you
+ * are using to enable to proper setup and features of your Skywire modem.
+ *
+ * NOTE: Make sure the other Skywire modems listed are commented out.
+ *
+ * 2. Change the "DeviceID" to a unique identifier for your Nucleo board. One recommendation
+ * would be to use the MEID/IMEI of your Skywire Modem.
+ *
+ * 3. If applicable, change the APN for your Skywire Modem.
