This fix fixes a couple of issues in Get Started docs' Step Four:
1. `Sending build context to Docker daemon 158.8 MB` should be
`Sending build context to Docker daemon 2.048 kB` as there is only
one Dockerfile for context.
2. There are only 3 steps altogether in stead of 4 steps as
`RUN apt-get -y update && apt-get install -y fortunes` is one step.
So `Step 3 : RUN apt-get install -y fortunes` should be removed and
`Step 4 : CMD /usr/games/fortune -a | cowsay` should be changed to
`Step 3 : CMD /usr/games/fortune -a | cowsay`
