Working with this code, I want to be able to set it up locally for the most basic smoke tests before rolling out any changes.

I'd like the README.md to contain a how-to for setting the code up in a development environment locally.
I'd also be happy with another solution, like mkdocs for developers, but that is not necessary, really.

I'll start to document any solution for a local set-up I come up with on my own, but even so, help would be greatly appreciated.
