+The Internationalization (i18n) plugin allows Strapi users to create, manage and distribute localized content in different languages, called "locales". For more information about the concept of internationalization, please refer to the [W3C definition](https://www.w3.org/International/questions/qa-i18n.en#i18n).
+
+## Features
+
+- Admin panel users can create several localized versions of their content
+- Developers can build localized projects by fetching and consuming the right content depending on the country/language of the audience
+
+## Installation
