Tutorials on Unity Learning

Hi,

I want to subscribe to Unity Learning; got a cheap voucher from Humble Bundle; but I don't want to activate it until I see more of the native AR Foundations being demonstrated, and VR tutorials. Does anything know of any learning resources/demos of AR Foundations? I've been through plenty of Vuforia tutorials on Udemy- but I don't want to get Vuforia, and am not interested in $$$Wikitude$$$; because AR foundations should replace them.
