-              <p>You must manage the position of a pinned element and the behavior of its immediate parent. Position is controlled by <code>affix</code>, <code>affix-top</code>, and <code>affix-bottom</code>. Remember to check for a potentially collapsed parent when the affix kicks in as it's removing content from the normal flow of the page.</p>

+                Affix toggles between three states/classes: <code>affix</code>, <code>affix-top</code>, and <code>affix-bottom</code>. You must provide the styles for these classes yourself (independent of this plugin).
+                The <code>affix-top</code> class should be in the regular flow of the document. The <code>affix</code> class should be fixed to the page. And <code>affix-bottom</code> should be positioned absolute. Note, <code>affix-bottom</code> is special in that the plugin will place the element with js relative to the <code>offset: { bottom: number }</code> option you've provided.
