Contributing guidelines

[daspecster]

Hello!

I was looking at the issue_template.md file that @liquidpele added recently. Great addition btw!

I noticed that we don't have contributing guidelines for this repo.

Do we inherit from the Celery guidelines or should we add our own CONTRIBUTING.rst/md file for this repo?

Well, I think we inherit most of the generic stuff, but a contributing file for this repo that's specific to us would probably be helpful for things like how to run our tests, common gotchas that are specific to django, etc.

I tried to setup a dev environment by using the given docker-compose.yml file in the repo (running docker compose up in the repo's root folder), but I get,
