 MDC Ripple provides the Javascript and CSS required to provide components (or any element at all) with a material "ink ripple" interaction effect. It is designed to be efficient, uninvasive, and usable without adding any extra DOM to your elements.

 But as far as we know, no browsers yet support it. We have added a `@supports` clause into our code
 to make sure that it can be used as soon as browsers adopt it, but for now this means that _changes
 to your theme via a custom variable will not propagate to ripples._ We don't see this being a gigantic issue as we envision most users configuring one theme via sass. For places where you do need this, special treatment will have to be given.
+
+### The util API
+
+External frameworks and libraries can use the following utility methods when integrating a component.
+
+#### util.supportsCssVariables(windowObj) => Boolean
+
+Determine whether the current browser supports CSS variables (custom properties).
+
+#### util.applyPassive(globalObj = window, forceRefresh = false) => object
+
+Determine whether the current browser supports passive event listeners, and if so, use them.
+
+#### getMatchesProperty(HTMLElementPrototype) => Function
+
+Choose the correct matches property to use on the current browser.
+
+#### getNormalizedEventCoords(ev, pageOffset, clientRect) => object
+
+Determines X/Y coordinates of an event normalized for touch events and ripples.
