    <ProseNote to="https://github.com/nuxt/ui/tree/v3/src/runtime/locale" target="_blank">
      If you need additional languages, you can contribute by creating a PR to add a new locale in <ProseCode>src/runtime/locale/</ProseCode>.
    </ProseNote>
    <ProseTip>
      You can use the <ProseCode>nuxt-ui</ProseCode> CLI to create a new locale:

      <ProsePre language="bash">nuxt-ui make locale --code "en" --name "English"</ProsePre>
