You can either using skype, share your screen and run through the pages of ReMe with them, or you can again with skype, just run the ReMe overview video from this page and as presented above.
This makes is easier to demo ReMe at the beginning of your learning process. Later on you will probably want to adopt your own style.
We would prefer that you do not leave a link/copy of this video with them as we are protective of the full knowledge of ReMe being generally available to those other than protective clients.
Having said the above its often better to visit the client since getting to know them is always valuable, and indeed fun
