At a later date, I'll post some contributor guidelines and templates, but since this project is in its early days, I have yet to have a significant amount of time in terms of thinking of this. However, some of the things to keep in mind are:
 - Be sure to adhere to the [Swift API Design Guidelines](https://www.swift.org/documentation/api-design-guidelines/) when contributing code.
 - When writing documentation, make sure it's clear, understandable, and comprehensible enough for users (both experienced and new) to understand it.
 - Try to follow the [Git commit best practices](https://cbea.ms/git-commit/).
