 Once you're done installing peer dependencies, that's it! The plugin will attempt to locate a `babel.config.js` file or a `.babelrc` file and use the options, plugins, and presets found there.
 By default, some combination of presets and plugins will be applied depending on the config options you provide, while others will be forced at all times for interoperability reasons. See [this section](#default-babel-plugins) for more details.

+
+If you don't want this behavior, simply pass the `browserslist: false` option to the plugin. Doing so will never apply `@babel/preset-env` and not apply any additional syntax transformations:

 #### Special handling for minification plugins/presets
 
 This plugin will apply syntax transformations from Babel presets and plugins on a file-by-file basis. However, if a minification-related plugin or preset such as [babel-preset-minify](https://github.com/babel/minify/tree/master/packages/babel-preset-minify) is found within the Babel options,
