+description: multi threading library
+layout: doc

+
+## Introduction
+Yarn is a simple multithreading library. Threads are individual Lua states,
+so they do NOT share the same environment as the code that runs the thread.
+
+Example:
+
+```lua
+local yarn = require 'yarn'
+
+-- calling t will run the yarn thread.
+local t = yarn.thread(print)
+t 'printing from another lua state!'
+```
+
+## Functions
+|||
+|----|----|
+|<a href="#yarnthread">thread(fun) -> @Thread</a>|Creates a new, fresh Yarn thread.|
+
+<hr>
+<div id='yarnthread'>
+<h4 class='heading'>
+yarn.thread(fun) -> <a href="/Hilbish/docs/api/yarn/#thread" style="text-decoration: none;" id="lol">Thread</a>
+<a href="#yarnthread" class='heading-link'>
+	<i class="fas fa-paperclip"></i>
+</a>
+</h4>
+
+Creates a new, fresh Yarn thread.  
+`fun` is the function that will run in the thread.  
+
+#### Parameters
+This function has no parameters.
