Deploy to docker cloud button

Hi -
I don’t seem to be able to get the “Deploy to Docker Cloud” links working from a subdir in a docker repo - eg in the repo: https://github.com/psychemedia/disposableAppShelf/tree/master/dataApps/OpenRefine . Any hints as to what I’m doing wrong (probably a simple “can’t see the wood for the trees” thing?!)

thanks
