Project-wide documentation for Exercism.
First of all, thank you for helping with Exercism.io!
We are working to improve this documentation. If you find any part of it confusing, or if you can't figure out how to get started with something, then rest assured it's not you, it's us! Please open up a new issue to describe what you were hoping to contribute with, and what you're wondering about, and we'll figure out together how to improve the documentation.
