If you want to edit the content of the checkout you can do this by additional customization. Checkout files, which are rewritten in our theme, can be found in legenda/woocommerce/checkout folder. Please do all changes via child theme to prevent losing them after theme update. If you don’t have the necessary skills you can submit customization request to WPKraken team or contact WC support. Also, you can maybe find a plugin that can provide this functionality.
