 ## Overview

+</Preview>
+
+For React usage, `ProgressIndicator` holds the `currentIndex` state to indicate
+which `ProgressStep` is the current step. The `ProgressIndicator` component
+should always be used with `ProgressStep` components as its children.
+
+Changing the `currentIndex` prop will automatically set the `ProgressStep`
+components props (`complete`, `incomplete`, `current`). For general usage,
+Progress Indicators display steps in a process. It should indicate when steps
+have been complete, the active step, and the steps to come.
+
+If you register an `onChange` handler, the Progress Indicator will become
+interactive. Your parent component should update the `currentIndex` prop within
+the `onChange` handler.
