1. Select the language you want to translate and choose the notification.
2. You can use the 'Import from Original' feature to simply copy the complete original notification.
3. Then replace the text with our translations and save.
Please note: It might be necessary to touch your original Shopify notification to enable those in langify. (just add whitespace)
