Precompile Material Design For Web

I am going to be using Material Design For Web in a PHP application with a custom theme. I am looking for instructions on how to precompile the JS and CSS with my custom theme variables so that I can just pull in the js and css like you would if using the CDN. It appears the CDN does offer some custom themed color options, but none look like what I am looking for which is why I am looking to create my own precompiled css and js files

What are the steps to precompile with the custom theme variables so that I can just have a dist css and js file?
