We need to provide a simple deployment way. Ideally people who want to try the journal should be able to make a DigitalOcean deployment in a few minutes.

Daniel yesterday suggested using dokku, which is like a mini-heroku implementation.. that gives you all freedom.

Let's investigate what we need and if dokku can help us.
