How to share my environment variables with open source projects?
I generally include a "run" script, which is in charge of:

setting the right environment variables
check the PATH for execution environment dependencies (making sure you have the right minimum version of some executable required to run your project)
running the actual project.
Hi so I'm new with running an open source project. Currently, I want to let other people contribute to my project, but I'm running into a problem right now. How would I share my environment variables which other users to make sure that their app runs locally. Is there a way to have contributors run my project locally without having all of their environment variables configured? I thought of having the person make their own environment variables, but since I have quite a bit of environment variables, I would like to avoid that. 
Note: I'm running a Flask App for my backend.
