swift-style-guide/CONTRIBUTING.md

This guide is primarily intended to be descriptive, detailing the usage that Swift developers at GitHub have arrived at in cases of disagreement. Consider whether a proposed addition would make more sense in a fork used by your projects/organization instead.

If you want to suggest a change or addition that will help accomplish the goals of this style guide, please open a pull request that:

1. Explains the guideline
2. Demonstrates the guideline with more-or-less valid example code
3. Justifies the guideline by explaining the rationale behind it

Just note that all suggestions are open to discussion and debate! 😄
