Instructions on deploying from a private Github repo

[rossettistone]

Having a tough time figuring out where to hook up my SSH key so that the remote server can pull from my private repo. Would be great if instructions for this were included in this tutorial.

Any hints appreciated! Otherwise I'll try to put together a PR for this when I figure it out.

Sorry I don't have time to update the guide right now but there is a comment on my blog that gets at the basics of how to do this (see the second to last comment on my blog.

A PR to clarify that part would be much appreciated.
