Ports not mapping, documentation beneficial. #29

Just chased an unusual problem where Port 21 was not forwarding to the host, but accessing the docker 172.x.x.x image directly would answer back.

Turns out, the reason is I was using docker-compose and "When mapping ports in the HOST:CONTAINER format, you may experience erroneous results when using a container port lower than 60, because YAML parses numbers in the format xx:yy as a base-60 value. For this reason, we recommend always explicitly specifying your port mappings as strings."

While not a specific problem with this image, it may be wise to add a note or to show the port mapping in quotes in the example.
