@djtfmartin can you review please? README.md is currently visible on develop branch.

Thanks Simon.

This is probably more a comment on the ansible setup. I'd like to remove the need for a yml file and just stick with using the inventory for setting up username/password deployments. This is how the other playbooks where done.

For local vagrant installs this root/password is just fine. For other system prod/dev/test these values should be in inventories stored in a private repo.

For the rest of the README, the following would be good:

1. graphic of the current schema
2. list of technologies in use
3. a simple architecture diagram for the deployment (nothing complicated)

bumping this to the next version.

@sbearcsiro is this done? Can I close?
