+`@prefresh/vite` configures Vite's Oxc JSX transform for Preact and composes
+`@prefresh/rolldown` internally. Babel is only used as a selective fallback when
+you pass `parserPlugins`.
+
 ## Options
 
 The plugin accepts two options `include` & `exclude` which are used in the [`@rollup/pluginutils.createFilter`](https://github.com/rollup/plugins/tree/master/packages/pluginutils#createfilter) to filter out files or include them.
 
-The plugin also accepts the addition of [`parserPlugins`](https://babeljs.io/docs/en/babel-parser#plugins)

+Providing `parserPlugins` opts that file transform back into the Babel-based path,
+similar to how `@preact/preset-vite` only enables Babel when that path is requested.
 
 ## Best practices
