https://github.com/pythonanywhere/help_pages/blob/master/articles/EnvironmentVariables.md
mentions how to load environment variables in your web application or in your virtualenv consoles.
However, not everyone uses a virtualenv and there is no documentation to address loading the environment variables into a normal bash console.
I discovered you just need to add set -a; source ~/my-project-dir/.env; set +a to the .bashrc file that's at /home/username/ so it shouldn't be hard.
I think this would make the article more complete, I could open a PR if you want but I wanted to run this past you guys first :)
