+        Each component that is publicly available can be viewed in our
+        Storybook. Each component folder contains an example of the component
+        variants, its skeleton state, and a playground.

+      <p>
+        The <code>Playground</code> story allows users to dig in to specific
+        props that are available to that component. This allows you to view the
+        component in different states and with different data values. To access
+        these props, navigate via the <code>knobs</code> tab at the bottom of
+        the canvas. Keep in mind, not all props are hooked up into the knobs
+        tab. For a comprehensive list of props available for each component,
+        refer to the <a href="#docs">Docs tab</a>.

+      <h3 id="actions">Actions</h3>
+      <p>
+        Within the <code>Playground</code> story, you can also access the
+        <code> Actions</code> tab, which shows the event signature of actions
+        taken on that component

+      <h3 id="docs">Docs</h3>
+      <p>
+        Each React component also has an MDX file containing more in-depth
+        documentation regarding specific props or common functionality. To
+        access these, click the <code>Docs</code> tab at the top of the screen.
+        This is also where the component API can be located.
