[ale] Does anyone have any experience actually running Docker?

[Kyle Brieden]

I tried to go through the official documentation, but it was confusing, 
and seemed to only describe running something called "docker-machine".  
It didn't however, describe what docker-machine is, nor does it give a 
set of information on how to do it on Linux.  What irked me was that 
docker-machine is windows/mac specific.  It just was frustrating to try 
to fumble through, and it raised more questions for me than it answered.
