Why should you read this over other Flask tutorials?

Simplicity and Predictability are important characteristics of a Flask structure that allows you to iterate quickly. Take a look at the end product (what you'll be building) on Github to get a view of what this means:

I've used different Flask structures in the past, ranging from a single massive file to a modular app with Blueprints. I've found that this structure works well for startup/indiehacker type projects where requirements keep changing so a flexible, simple and predictable structure is crucial.
