I want to use only *.cpp files and no *.ino anymore. I read a lot of stuff about how to upload c++ instead of arduino sketches. But still I did not found the step by step guide how to do it.

Actually I am developing my sketched withing Spacemacs (Emacs) and uploading it with Arduino-Makefile (https://github.com/sudar/Arduino-Makefile)

When I now want to start a new project with only *.cpp and *.h files to use classes etc. how would I start? Does anybody has the time to describe a rough step-by-step without the trivial stuff?
