This doesn't seem to give me a single clue on what it does past the initial change of:
hub clone rtomayko/tilt
Am I missing something? hub clone rtomayko/tilt
Am I missing something? hub pull-request
hub fork # adds remote automatically
hub create # create GH repo for this local repo
And ability to use GH paths anywhere git takes a URL - clone (as you mentioned), remote add, submodules, etc.
