I had to read the original paragraph a few times and search for docs on the file's purpose to understand what this step entailed. So here's another try at an explanation of what to do and why, with a hint about best practice.
- wrap lines in the java and golang getting started
- make the "test on the host" step in the Java getting started "optional". This
allows users to try the tutorial without requiring them to set up a functional
Java environment on their host. (i'm planning on making similar changes in
the other language guides).
- use `docker <object> <action>` in some examples (but mention the corresponding
shorthands); this may help understand the relation between the `<action>` and
what kind of `<object>` we're acting on (tag an _image_, remove an _image_).
