Yarn is a language that's designed to make it super easy to create interactive dialogue for games. Yarn's very similar in style to Twine, so if you already know that, you'll be right at home! If you don't, that's cool - Yarn's syntax is extremely minimal, and there's not much there to learn. The Yarn language is used in a number of cool games, including Night In The Woods and Knights and Bikes.

Yarn Spinner interprets the Yarn language, and is written in C#. Yarn Spinner is designed to be easy to add to Unity games, but it's also intended for use in other contexts as well.

Important: Yarn Spinner is still under development, and we haven't made our 1.0 release yet. It's probably fine to use right now, but there are a few bits and pieces that might change between now and first release.
