 `vue-web-component-wrapper` is a powerful Vue 3 plugin designed for transforming full-fledged Vue applications into reusable web components (custom elements). These web components can be integrated into any website, enhancing flexibility and reusability.
 
 ## Why use `vue-web-component-wrapper`?
-As of now, Vue 3 does not support the creation of full aplication as web components out of the box. This plugin aims to solve this problem by providing a simple and easy-to-use solution for creating web components from Vue applications. It also provides support for Vue ecosystem plugins such as Vuex, Vue Router, and Vue I18n.

+## New Feature Highlight: Replace `:root` with `:host`
+Our latest feature allows you to automatically replace `:root` selectors with `:host` in your CSS styles. This is particularly useful when working with CSS frameworks or custom styles that define variables or styles on the `:root` selector. By replacing `:root` with `:host`, these styles are correctly scoped within your web component's Shadow DOM.

 ## Tips
-- **Testing Production Build**: the easiest way to test your production build is to run a local server in the `dist` folder. I use [valet](https://laravel.com/docs/10.x/valet) for this, but any local server should work.
