The shader is very simple to use and self explanatory. I have also made a youtube video that has a detailed step by step on how to install and use this Asset Bundle and Shader. 

To install categorized:

    Remember to open this file in its own folder with the blender_assets.cats.txt file in the same folder 

    The Asset Library should have a button that says Copy Bundle to Asset Library

    Click on the button and it will ask you to save the file in your asset library location

    Once you save it in your asset library, the catagories and thumbnails should be added to your library

    To install uncategorized

    Place only the blender file in your asset folder. 

    Open the file and the materials will be located in your asset library under uncategorized.
