 ## Installation
 
 Install `carbon-preprocess-svelte` as a development dependency.
 
 ```sh
-# Yarn
-yarn add -D carbon-preprocess-svelte
-
 # npm
 npm i -D carbon-preprocess-svelte
 
 # pnpm
 pnpm i -D carbon-preprocess-svelte

 ## Usage
 
 - [**optimizeImports**](#optimizeimports): Svelte preprocessor that rewrites Carbon Svelte imports to their source path in the `script` block, making development compile times dramatically faster.
 - [**optimizeCss**](#optimizecss): Vite/Rollup plugin that removes unused Carbon styles, resulting in smaller CSS bundles.
+- [**OptimizeCssPlugin**](#optimizecssplugin): The corresponding `optimizeCss` plugin for Webpack that removes unused Carbon styles.
 
 ### `optimizeImports`
 
-`optimizeImports` is a Svelte preprocessor that rewrites barrel imports from Carbon components/icons/pictograms packages to their source Svelte code paths. This can significantly speed up development and production build compile times while preserving typeahead and autocompletion offered by integrated development environments (IDE) like VS Code.
