+## Experimental:

+This library also exposes a `hohoro-experimental` binary that builds code using [oxc](https://oxc.rs/) with [`oxc-transform`](https://www.npmjs.com/package/oxc-transform).

+When using the experimental binary - you'll **need to also install `oxc-transform` as a devDependency**.

+```
+
+You **do not need additional configuration** when using the experimental build.
