1.) 	Edit the config.php using your favourite text editor. All settings are commented inside.

2.) 	Upload the files into a subfolder like "paypal".
	The name of the subfolder is not important - you can rename it - but the directory 
	structure should look like:
	/iredirector/
	/iredirector/admin/
	/iredirector/paypal/

3.)	Run the install.php. This will create a new table where the PayPal payments will be logged.
	When a payment is completed, the PIN will be added to the already existing iRedirector 
	table and an email will be sent to the customer containing that PIN. That is done by the 
	file paypal-backend.php. we have added several security checks, so it should be quite 
	impossible to get a PIN without actually paying through PayPal.
	By the way you will of course receive an email if anything goes wrong processing an order.

4.)	Go to your iRedirector Admin Interface and choose "Add/Update Domains" from the 1st drop 
	down menu. Edit the domain of your choice and select "Require PIN Code" = yes. "Your Order
	URL" is the URL of your paypal.php, e.g. http://www.domain.com/iredirector/paypal/paypal.php
