-
-<li><dfn>system/codeigniter</dfn></li>
-<li><dfn>system/database</dfn></li>
-<li><dfn>system/helpers</dfn></li>
-<li><dfn>system/language</dfn></li>
-<li><dfn>system/libraries</dfn></li>
-</ul>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-<h2>Step 2: Update your user guide</h2>
-<p>Please also replace your local copy of the user guide with the new version.</p>
