Build PowerMonkey

DISCLAIMER

I merely provide you a script to build PowerMoney EFI because it is not the easiest task. Using these EFI binaries are potentially dangerous and could damage your computer. I am not responsible for any damages that might cause. Use at your own risk.

A blog post is written for this repository.

These scripts are created to ease the so many steps to build PowerMonkey. If you do not understand what you are doing, you probably shouldn't be running this. Read about EFI and boot process. PowerMonkey github has a good explanation.
