 			<h1>AlwaysKillSticky Help</h1>
 			<p>On sites/pages where it’s enabled, AlwaysKillSticky finds all elements whose <code>position</code> CSS property has a computed value of either <code>sticky</code> or <code>fixed</code>, and removes those elements.</p>
 			<h2>Basic usage</h2>
-			<p>To enable AlwaysKillSticky on a site, click the AlwaysKillSticky icon in your browser toolbar, then click the big button (shaped like a thumbtack: <span class='fa fa-heavy'>&#xf08d;</span>). Stickies will immediately be killed, and will always be killed whenever you visit that page, or any page on the same site, in the future.</p>
-			<p>To stop killing stickies on a site, just click the big button again. Stickies will no longer be killed when you visit pages on that site. (After disabling sticky-killing for a page, you can click the Reload (<span class='fa fa-heavy'>&#xf2f1;</span>) button to refresh the page if you want to restore killed sticky elements on that page.)</p>
+			<p>To enable AlwaysKillSticky on a site:</p>
+			<ol>
+			<li>Click the AlwaysKillSticky icon (<span class='fa fa-heavy'>&#xf08d;</span>) in your browser toolbar;</li>
+			<li>Click the big button (<span class='fa fa-heavy'>&#xf08d;</span>).</li>
+			</ol>
+			<p>Stickies will immediately be killed, and will always be killed whenever you visit that page, or any page on the same site, in the future.</p>
+			<hr/>
+			<p>To <em>stop</em> killing stickies on a site:
+			<ol>
+			<li>Click the big button (<span class='fa fa-heavy'>&#xf08d;</span>) again.</li>
+			</ol>
+			<p>Stickies will no longer be killed when you visit pages on that site.</p>
+			<p>(After disabling sticky-killing for a page, you can click the Reload (<span class='fa fa-heavy'>&#xf2f1;</span>) button to refresh the page if you want to restore killed sticky elements on that page.)</p>
 			<h2>Modes</h2>
 			<p>AlwaysKillSticky can work in either of two modes: <strong>blacklist mode</strong> (the default) and <strong>whitelist mode</strong>. (You can switch modes at any time, via the Options page.)</p>
