modified docker commands for ease of use

[themegabyte]

Hello,

I figured I would add some (and simplifiy one) docker commands if someone was trying to run it off of docker.

I goofed my other username while commiting, but let me know if that is an issue. I will submit another pull request.

Thanks.
