 `rootDir` | `.` | The root directory of the application to bundle.
-`prerender` | `false` | Pre-render every route of your application. (**note:** This is an experimental flag. The behavior might be changed.)
+`--prerender` | `false` | Pre-render every route of your application. (**note:** This is an experimental flag. The behavior might be changed.)
+`--dotenv` | `.` | Point to another `.env` file to load, **relative** to the root directory.
