 # Quasar Unused Plugin
 
-This is a Webpack 5 plugin for tree shaking unused Quasar components from generated bundles. If you are using Quasar as a standalone UI library with Webpack, then you will be importing from `node_modules/quasar/dist/quasar.esm.prod.js`. However, Webpack cannot tree shake unused components from this file because this file contains circular references. We can instead import the source code from `quasar/src/index.prod.js` and use this plugin to break the dependency chain.
