There are a few different ways to translate your pages:
If you're using Shopify Markets, you can create Shopify Sections in Replo and edit them in the Shopify Theme Customizer, providing different translations on a per-market basis. You can also translate things like product titles, option names, etc using Markets. See 📄 Shopify Markets for more info.
You can use a third party app to translate your page content. See Translations and International Selling Integrations for more info.
