 ## Description
-This library provides a simple to use webgl shader component, with included framework wrappers and strong typing. Shaders are powerful tools and can be used to add a lot of visual interest to your web project. However, setting-up many shader tools can be complicated and add a large bundle to your project, this library provides a simple core package to make rendering a shader in your DOM incredibly easy.
