 Q:Why are build instructions for Arduino mess.
 
-Y:We are too lazy to ship proper board definition for Arduino. We plan to swich to cmake + ninja to be inherently multiplatform, easily integrate build tools, suport more IDEs, get 10 times shorter build times and be able to update compiler whenewer we want.
