     This file is completely optional.
     You only need this if you want to
     extend the base configuration - we add a dummy library here and define one additional build environment (board)
-   * [GwExampleTask.h](GwExampleTask.h) the name of this include must match the name of the directory (ignoring case) with a "gw" in front. This file includes our special hardware definitions and registers our task at the core (DECLARE_USERTASK in the code). Optionally it can define some capabilities (using DECLARE_CAPABILITY) that can be used in the config UI (see below).
-   Avoid including headers from other libraries in this file as this could interfere with the main code. Just only include them in your .cpp files (or in other headers).

    * [GwExampleTaks.cpp](GwExampleTask.cpp) includes the implementation of our task. This tasks runs in an own thread - see the comments in the code.
    We can have as many cpp (and header files) as we need to structure our code.
