Sketch problems

[oldage]

I am having trouble defining a sketch using the main.cpp tag of arduino-1.0.5-r2. I have defined my tricopter in the config.h tag of MultiWii_2_3 Since I don't understand the exact meaning (s) of all the code symbols, can someone show me the step by step changes I should make to main.cpp and using config.h to define the "setup" and "loop" to get a sketch that I can verify/compile without error using MultiWii_2_3. It would help if you could send me the exact form of main.cpp as it should be changed. If it would help, I could send you my email address. Thank you for your help.
