I can manually "run" other docker images, but I can't seem to get the documentation example to work:

What does docker version say? Does docker logs on the c1 container id say anything interesting? What happens if you docker start it manually?

@thebithead I think the readme mentions that docker versions newer than 1.6.2 arent supported. and you are on 1.8.1.

Would love to see a fix for newer versions of docker.

Closing this one as a duplicate of #14 -- the fix for which is coming shortly.
