+> :warning: For webpack v5 or above please use [css-minimizer-webpack-plugin](https://github.com/webpack-contrib/css-minimizer-webpack-plugin) instead.
+
 ## What does the plugin do?
 
 It will search for CSS assets during the Webpack build and will optimize \ minimize the CSS (by default it uses [cssnano](http://github.com/ben-eb/cssnano) but a custom CSS processor can be specified).
