 In addition to hosting translated content files, Starlight allows you to translate the default UI strings (e.g. the "On this page" heading in the table of contents) so that your readers can experience your site entirely in the selected language.
 
-English, Czech, French, German, Italian, Japanese, Portuguese, Dutch, Danish, Spanish, Turkish, Arabic, Norwegian, Farsi, Hebrew, Simplified Chinese, Korean, Indonesian, Russian, Swedish, Ukrainian, Vietnamese, and Galician translated UI strings are provided out of the box, and we welcome [contributions to add more default languages](https://github.com/withastro/starlight/blob/main/CONTRIBUTING.md).
