django errors using boot2docker tutorial

If you are doing the docker-compose / boot2docker tutorial on the docker site at:

There are a few typos and items that will stop you, at least on a Mac although I suspect they are an issue on a PC as well. These are my notes, out of context but hopefully they will help someone else having problems with errors and configuration of Django Dockers for their dev environment.

boot2docker up
docker-compose up
# the following line runs it in the background
docker-compose up -d
To connect the Docker client to the Docker daemon, please set:
 export DOCKER_HOST=tcp://
# this tells you your environment variables
docker-machine env
# The following is incorrect in the docs
docker-compose run web python composeexample/ syncdb

Rough notes, but hopefully enough to help you google for more if you are hitting the same wall I did with boot2docker and docker-compose for Django.
