Thank you for creating CONTRIBUTING.md. I think that this is a great first step, and will be leaving some comments later.

I think @nbougalis needs to review and approve this so a CONTRIBUTING.md is available in the repo.
The file seems useful for developers looking to contribute, perhaps make it look better as it looks messy as of now.

Closing in favor of #3955 which is better (both in formatting and content) - feel free to add / contribute over there.
