How to walk/move with Google Vr?

Hello and thanks for taking a look to my problem. Google Vr had appeared some weeks ago and there's not a lot of new scripts created for it. There is my problem, i've seen an autowalk has been developed for Google Cardboard and I think it's working very well but now, I can't get the google cardboard sdk (which has been replaced by Google Vr) so due to the fact that i'm not a "professional" in unity (i've only begun few weeks ago) and that the autowalk script is not compatible with the GoogleVr sdk, I hope that someone can bring me an answer or bringing a link to dowload the old Google Carboard sdk. Thanks!
