3. Copy the 'lib' folder from the source into your new iATS folder
4. Create a new file called iATS.php in your new iATS folder. Paste the following into it and save the file:

​require 'iATS/lib/Core.php';
require 'iATS/lib/ProcessLink.php';
require 'iATS/lib/CustomerLink.php';
require 'iATS/lib/ReportLink.php';

5. Now you can add a 'require' to wherever you need to use the iATS library:

​require 'iATS/iATS.php';
