This is, AFAIK, supposed to be used when working with stylesheets generated by WordPress for e.g. creating themes. The list provided by purgecss-with-wordpress can be used to easily safe list the default CSS rules required by WordPress for the general layout. To apply a config, that employs purgecss-with-wordpress, you could use the purgecss CLI as part of your e.g. build process or CI/CD.

Unfortunately, I'm not too familiar with WordPress development. But as far as I know, it's what @Chaostheorie said in the comment. This should work like any other development setup, where you will need to call PurgeCSS through postCSS, or Webpack, or another build tool. I could find one reddit question about it with some suggestions here
