EUI Template Reference: Provides descriptions of the main EUI templates that control how the EUI looks and functions.
Text and Localization in the EUI: Describes how the EUI facilitates localization and how you can configure your EUI to support multiple languages.
Legacy EUI Overview: Provides an overview and instructions for working with the Legacy EUI. However, we strongly encourage you to use the newer EUI because it contains a variety of enhanced functionality.
