Thanks. I was up in running in no time following those directions. Oddly enough the first few tries running hello world came back with 502 errors:

> root@docker:/proc# docker run base /bin/echo hello world Pulling repository base from https://index.docker.io/v1 2013/06/13 22:19:37 HTTP code: 502

After about 2 minutes it just started working. Was that a networking hiccup and on which side?
