Setup the COSMOS Repo and Improve the Setup Documentation

[CarsonDavis]

Description

Get the COSMOS repo running on your local environment.

Do this using the documentation provided in the repository, and if anything is badly documented, fix it to be more clear.

Implementation Considerations

• you can talk to @dhanur-sharma to get a database backup to load onto your system
• you will want to install some core technologies, such as python 3.10, docker, docker-compose, github cli

Deliverable

Updated documentation with improved contributing/installation procedure.

Dependencies

If you take a look at the CLI, you can spawn a feature branch off of this issue number. Instructions are in CONTRIBUTING.md. You will want to get started off the dev branch. Create a draft branch, turn it into a real pr when you are ready.

After you get COSMOS running, check out the django documentation at https://docs.djangoproject.com/en/4.2/intro/overview/. I would recommend you do the getting started guide.
