* Previous steps before starting

In most cases, you probably won't want to use any base image, and instead **build a container image from scratch** one based on the official Python Docker image.

Taking care of the **order** of instructions in the `Dockerfile` and the **Docker cache** you can **minimize build times**, to maximize your productivity (and avoid boredom). 😎
