 ```javascript
 depre('pre');
 ```
+
+Take for example the following `pre` tag nested inside a `div`:
+
+```html
+<div>
+    <pre>
+    {
+        "name": "CanvasToVideo",
+        "description": "An experiment in converting Canvas animations to video.",
+        "main": "CanvasToVideo.js"
+    }
+    </pre>
+
+</div>
+```
+
+The contents of the `pre` tag will render like this when viewed in a browser.
+
+```
+    {
+        "name": "CanvasToVideo",
+        "description": "An experiment in converting Canvas animations to video.",
+        "main": "CanvasToVideo.js"
+    }
+```
+
+With de-pre.js it will render like this:
+
+```
+{
+    "name": "CanvasToVideo",
+    "description": "An experiment in converting Canvas animations to video.",
+    "main": "CanvasToVideo.js"
+}
+```
