On the Shopify app store, you can find language apps that can translate your store into right-to-left (RTL) translations.
If you're confident editing Liquid code, create a right-to-left (RTL) template instead of using translation apps.
When you purchase a theme, it comes with a set of templates (e.g. Collections and Products). Shopify allows merchants to replace a theme's templates with new ones.
If you're not entirely confident making these changes yourself, we definitely recommend approaching a specialist in custom coding.
