Pixhawk firmware edit and build

hello,
i m new to pixhawk and its programming, doing editing in the firmware of px4 was a challenge for me but with the help of http://ardupilot.org/dev/docs/building-px4-with-make.html#building-px4-with-make i made the build environment but the problem is i want to import the px4 firmware in the eclipse software to make changes in it, but i m confused that which file should i import to the eclipse. where is the main project file in he firmware?

help will be appreciated.
thanks

Hello,

Did you clone the Ardupilot repo? If not, have a look Here. Once that’s done you’ll want to follow the steps Here.
