VS integration with gitHub

Hello.

I want to check out the sample applications but I'm new to gitHub. I've installed the "Git Source Control Provider" from NuGet, and also installed the Microsoft Git Provider. Why? Because I scouring the internet that's what I found.

Now that I have both installed, how to I "point" to a sample application and/or download it?

For example, what do I need to do to work with the "Tasky" sample app for Andoid?

Thanks in advance,

Mike
