Has anybody gotten this to work? Again i am not very familiar with github please be specific

Hi

You can link your Unreal account with GitHub by following these instructions:

Once you’re set up, Unreal GitHub site will show you repository for Unreal Engine. Hope that helps!

I have UE 4.7.5 with Leap Motion Plugin v0.9.2 but when i want open LeapExamples it still show me same message “This project requires LeapMotionControler plugin” Leap Motion Plugin v0.9.2
