Local dev setup

Resolves: #1

Description:

I worked through the local dev setup in the readme and made some fixes as I came across issues. It was already pretty good overall so I just made some minor fixs.

• Some dependencies were missing from requirements.txt
• There was misnamed environment variable
• The example query referenced a non-existent field
• Test instructions were missing I also added a shortcut to get postgres running locally if you have docker installed.

Tests:

No unit tests are required but it may be worth running through the steps again to confirm the changes make sense.

Thanks so much! If you have time, I'd love any help you'd like to give with #8, #30, or anything else that would get this project closer to being testable in a CI/CD pipeline! Either way, thanks again!
