+
+## Tooltip markup
+A standard tooltip
+
+    <div class="tooltip fade top in">
+        <div class="tooltip-arrow"></div>
+        <div class="tooltip-inner">Create a new blog post based on this</div>
+    </div>
+
+## Spawning tooltips
+Tooltips can be automatically created when the mouse enters an element using the `data-toggle="tooltip"` tag.
+

+        data-placement="left"
