How to have as well nvidia FleX & Hairworks with github?

I will firstly apologize for my level in english (I’m french). Is somebody knowing a way to get as the same time a version of the engine with Hairworks and FleX using the page given by Nvidia ( ).
I’m a beginner with github and it would be great if someone could explain me the way to do that.
Thanks you in advance for your help :slight_smile:
