+> To enable CSS processing in your project, you need to install [style-loader](https://webpack.js.org/loaders/style-loader/) and [css-loader](https://webpack.js.org/loaders/css-loader/) via `npm i style-loader css-loader`.

 `sass-loader` requires you to install either [Dart Sass](https://github.com/sass/dart-sass), [Node Sass](https://github.com/sass/node-sass) on your own (more documentation can be found below) or [Sass Embedded](https://github.com/sass/embedded-host-node).
 
 This allows you to control the versions of all your dependencies, and to choose which Sass implementation to use.
