# SA5 Core ❺ SA5 Core is the center of the SA5 library and provides centralized functionality to the rest of our library infrastructure. It provides; * Webflow design-time support * Certain core functions * Global variables & constants * Central datastore * Event handler registration and tracking {% hint style="info" %} Most of these capabilities are internal-facing and are probably not useful to Webflow designers and developers. However there are a few important features here that are particularly useful to advanced designers. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
