Installation of translations

Translations must be located in translations.

Files should be be named <domain>.<locale>.<extension>.

Examples:

translations/messages.de.yaml
translations/routes.de.po
translations/validators.de.xlf

After the files have been placed, you must 'install' them by going to "General Settings > Localisation settings".

This will update the /config/dynamic/generated.yaml file in order to indicate to the system that your new locale/translation is available.
