+    <h1>jQuery Plugin Demo: Are You Sure?</h1>
+    <p>
+      This page hosts a demo of the <a href="https://github.com/codedance/jquery.AreYouSure">jQuery Are-You-Sure</a> plugin (<code>jquery.are-you-sure.js</code>).  
+    </p>
+    <p>
+      <i>Are-you-sure</i> is simple light-weight "dirty forms" JQuery Plugin for modern browsers. It helps prevent users from loosing unsaved form changes.
+    </p>
+    <p>
+      <strong>Features:</strong>
+      <ul>
+        <li>Light weight - only the features you need!</li>
+        <li>Dependency free.</li>
+        <li>Correct state management - if a user edits then restores a value, the form is not considered dirty.</li>
+        <li>Easy to understand - less than a "terminal screen" of code!</li>
+        <li>... and <a href="https://github.com/codedance/jquery.AreYouSure">more</a>.</li>
+      </ul>
+    </p>
+
+    <h2>Example 1: It's simple!</h2>
+    <p>
+      This example shows how easy it is to add a dirty check to your form(s) with one line 
+      of code. (View the page's source)
+    </p>
+
+    <form id="example-1-form" name="coffeeOrder1" method="post">

+    </form>
+
+    <h2>Example 2: Ignore the unimportant!</h2>
+    <p>
+      This example highlights how to disregard a field from the dirty check. In this form
+      the first field is dynamically populated and hence a change on this field should <em>not</em> 
+      mark the form as dirty.
+    </p>
+    <form id="example-2-form" name="coffeeOrder2" method="post">
+      <h2>Enter Your Coffee Order</h2>

+
+
+    <h2>Example 3: Lets be intelligent!</h2>
+    <p>
+      This is a more advanced example.  The <code>dirty</code> and <code>clean</code> change events are 
+      intercepted so the save button is only enabled if the form is dirty (i.e. something to save). 
+      It also demonstrates how to customize the warning message and change the style of a dirty 
+      form (CSS styling using the <code>.dirty</code> class).

+    <h2>Example 5: Edge cases</h2>
+    <p>
+      This example demonstrates tracking of hidden and disabled form elements that are changed by non-input elements.
+      E.g.:
+    </p>
+    <ul>
+      <li>clicking a link or non-input button that changes the value of a hidden form field, or</li>
+      <li>
+        clicking a link or non-input button that enables or disables some form fields (which has an effect on whether
+        or not those fields will be submitted with the form, despite the values not changing).
+      </li>
+    </ul>
+    <form id="example-5-form" name="coffeeOrder5" method="post">
