Let's make the first page a more linear story of setting up a dev env on your local laptop. After installing the code, it should include all database creation commands. dev only usage of the ENV variable and then a walkthrough of filling in the createconfig for that environment.

The second page for the server can stay much the same, but should guide you through setting up a alternative prod env after creating the server and database in the cloud with Fabric

Things we probably need yet:

• Do we need to tell people to migrate their production database after bootstrapping?
• We should probably tell people to make another set of S3 buckets for production
• We should give an example of where you live website will be running
• We need to explain how django bakery works at some point
