Can the template support languages other than English?

Yes, the template can now support languages other than English.

How it works

When the customers visit the BYOB bundle page, the app will detect the active language of your store
If the locale is supported, the corresponding language will be displayed
Otherwise, the page always fallbacks to display English

Supported languages:

English
Japanese
Spanish
Traditional Chinese
French
German
Polish

You can change the translation in the Langauge Editor. Just visit BYOB => Settings => Change Text. You'll be redirected to the language editor in Shopify admin.

The translation format:

{quantity} is the variable we put in. Include {VARIABLE} in your translation
the pipe | is for pluralization, the left side is a single unit, the right side is for multiple units

p.s. Traditional Chinese is mainly used in Hong Kong and Taiwan, not China.
