Showing "$$ exit 13" caught my eye and wasn't correct.
While in there I also made it so the following paragraph didn't go past 80 chars

## Examples
$ docker run --name test -it debian
$$ exit 13
exit
root@d6c0fe130dba:/# exit 13
$ echo $?
13
$ docker ps -a | grep test

In this example, we are running `bash` interactively in the `debian:latest` image, and giving
the container the name `test`. We then quit `bash` by running `exit 13`, which means `bash`
will have an exit code of `13`. This is then passed on to the caller of `docker run`, and
is recorded in the `test` container metadata.
This example runs a container named `test` using the `debian:latest`
image. The `-it` instructs Docker to allocate a pseudo-TTY connected to
the container's stdin; creating an interactive `bash` shell in the container.
In the example, the `bash` shell is quit by entering
`exit 13`. This exit code is passed on to the caller of
`docker run`, and is recorded in the `test` container's metadata.
