Dockercloud button - launch Dockerfiles down directory path?

[psychemedia]

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?!)

I tried asking on docker forums, but all seems quiet there...
