   <title>Scrollbar preferences</title>
 
-<!-- Add some text here please. -->
+  <p>A scrollbar is a part of the Graphical User Interface (GUI) which allows
+  anything continuous and exceeding the visible screen space such as text to be
+  viewable by the user by scrolling down to the parts hidden from current
+  view.</p>
 
-<!-- Followed by some <steps> that contain instructions. -->
+  <p>Scrollbars are usually placed at either sides of the viewing area as long
+  rectangualr areas containing a bar that can be dragged along the track to move
+  the body of the text. Scrollbars also contain arrows on either end of this
+  track to for precise adjustments.</p>
