Intro

Django (https://docs.djangoproject.com/) is a fantastic web framework that allows you to develop web sites and web apps at pace, but rolling it out on Ubuntu (https://ubuntu.com/) can still be a bit of a pain. That is why I created this file.

Notes

Each line is prefixed by the environment you should run it in. A dollar ($) is Bash\shell\terminal. Triple greater-than (>>>) is the python shell (or the django shell). A hash (#) is the shell for Postgres.

$ something
$ something

$ something else

Spaces (or 'new line spaces' if you like) exist between different bits of work (project setup, installing packages, apache, etc...)

...

Dots with empty lines before and after indicate that this is not a necessary step but you might want to do it (They are found towards the bottom. E.g. setting up postgres (https://postgresql.org/), setting up certbot (https://certbot.eff.org/))
