+steps to be taken to allow this example to work :
+this file will be updated as I progress and recover the data from experience.
+
+1. Download and install the Arduino IDE { we are now at version 1.8.5 }
+
+2. when attempting to build errors will occur due to missing file Cube.h . To fix this we need the library
+
+2.1 Download the ZIP from the freetronics github repo site (even on Linux) and unzip into "libraries" in the tree where the IDE was installed. 
+
+3. restart the IDE - fine but the compiler enforces stricter rules now than when the example was created.
+
+4. Note : I already had a fork of the repo in ECA.
+
+5. So I removed the "unzipped" file from the repo as it has no version control and used the repo from the ECA user in github. I changed the files to make the compilation work and will now investigate further to merge them, when acceptable, into the mastaer...
+
+6. There are still several warnings at compile time with the Cube code. I will attempt to fix them.
+
+7. be aware that if you repeat the compilation then with some environment settings the warnings will 'go away' and it will appear clean...
