 # Helium Basic Example
 
 Here you will find a very basic example of a WisBlock/Helium embedded project that uses the Arduino IDE.
 This version will join the Helium network and periodically send a "Hello" to the Helium network.
 
+## Support Library Version Incompatibility
+Recent API changes to the runtime support library, SX126x-Arduino, have resulted in library version incompatibility between version 1.3x and version 2.x.
+
+| :warning: WARNING: This will require changes to the Arduino IDE installation, in particular the installed board support package files. The complete details of the changes required can be found [here](https://github.com/beegee-tokyo/SX126x-Arduino/blob/master/README_V2.md).|
+|:---------------------------|
+
+In addition to the IDE support file changes there are two major changes at the device application level if you are moving from verion 1 to version 2 of the support library:
+* The lmh_init() API requires 2 more parameters
+* the device application is no longer required to call Radio.IrqProcess() within it's main processing loop. The processing will now be handled by the runtime layer.
+
+The sample .ino file has been updated to be compatible with version 2 of the support library.

 ### Hardware
 The only hardware required is:
 * the [WisBlock Starter Kit](https://store.rakwireless.com/products/wisblock-starter-kit) containing  the base board with the core module installed.
