This is the project featured in the Django from first principles series on Mostly Python.
Most Django tutorials and resources use the standard approach of beginning a new project with django-admin startproject, followed by manage.py startapp. For experienced Django developers, this is a good approach. For people new to web development however, it creates a lot of complexity right at the start of the project. The Django from first principles series builds a simple but nontrivial project, starting with a single file.
