 ## Updating language tags
 
 sul-embed uses the IANA language subtag registry to resolve user-provided file language codes (e.g., 'en-US') onto user-friendly labels (e.g., "English"), primarily for captions in the media player. This file lives on the web and changes every so often. We cache this file in `vendor/data/language-subtag-registry`, and it can be updated via `rake update_language_tags`.
