How can I clone a set of colors from Google?

This site tells me that in order to use this color picker I need to clone them - the project repo. But I don't have git. Can I use them? I have never encountered using git or knew about it.

If I can use this - which one should I use? I accept the recommendation of My min API 19 - target API 25.

EDIT: Step 1: I am pasting the git command. And go to - new -> import module.

Step 2: Stuck with this solution - (I cut out the cloning project folder by pasting it outside) And import the new module

I tried to sync the project but the error is

dependencies {  
compile project(':colorpicker')}
