How to add micro-ecc library?

[Newbie]

I want to add micro-ecc library for compiling bootloader secure code. I tried as mentioned on infocenter.nordicsemi.com/index.jsp . I am getting error as attached. I am facing problem in cloning the github library in my folder. Can you please show me with screen shots to implement this? error.PNG

The screen shot of my files is also attached. files.PNG

Try to rename the folder micro-ecc-master to micro-ecc, and make sure that the micro-ecc source files are not placed in a subfolders inside this folder.
