Your right in saying the README is limited. What platform are you on?
I'm using Ubuntu 12.04, when I create a Arduino project, I have difficulty uploading my project to my arduino.
no problem using Terminal:
$ cd <path to project>
$ make clean
$ make upload
using the terminal I can compile and upload my project to the arduino but have not yet found out how to upload via Qt Creator.
btw installing gtkterm is helpful when using 'Serial.println();'.
getting this error:
/usr/share/arduino/Arduino.mk:513: build-cli/depends.mk: No such file or directory
