How do I download github source code for U4?

I am setting up samsung Gear VR and from what I have been reading it says to link github to the Unreal 4 account. Which I don’t see where that is supposed to be completed at. So can anyone help? or even send me images please. Email me would help too! growapearstudio@gmail.com

Go to main website www.unrealengine.com, log in to your account, then click on the account button on the up right, then you will see your account detail, click on the profile then you can link your github account name there.

Sorry for the messy, just a quick snipping ^^
