############################# Upgrading from 1.6.0 to 1.6.1 #############################

Before performing an update you should take your site offline by replacing the index.php file with a static one.

Step 1: Update your CodeIgniter files

Replace these files and directories in your "system" folder with the new versions:

• system/codeigniter
• system/database
• system/helpers
• system/language
• system/libraries

.. note:: If you have any custom developed files in these folders please make copies of them first.

Step 2: Update your user guide

Please also replace your local copy of the user guide with the new version.
