 [Omnipay](https://github.com/thephpleague/omnipay) is a framework agnostic, multi-gateway payment
 processing library for PHP 5.3+. This package implements eWAY support for Omnipay.
 
+[eWay](https://eway.io/about-eway) was launched in Australia in 1998 and now operates payment gateways
+in 8 countries.
+
 ## Installation
 
 Omnipay is installed via [Composer](http://getcomposer.org/). To install, simply add it
@@ -31,10 +34,19 @@ And run composer to update your dependencies:
 
 The following gateways are provided by this package:
 
-* Eway_Rapid
-* Eway_RapidShared
-* Eway_RapidDirect
-* Eway_Direct
+* Eway_Direct -- This gateway is deprecated.  If you have existing code that uses it you can continue
+  to do so but you should consider migrating to Eway_RapidDirect
+* Eway_RapidDirect -- This is the primary gateway used for direct card processing, i.e. where you collect the
+  card details from the customer and pass them to eWay yourself via the API.
+* Eway_Rapid --  This is used for eWAY Rapid Transparent Redirect requests.  The gateway is just
+  called Eway_Rapid as it was the first implemented.  Like other redirect gateways the purchase() call
+  will return a redirect response and then requires you to redirect the customer to the eWay site for
+  the actual purchase.
+* Eway_RapidShared -- This provides a hosted form for entering payment information, other than that
+  it is similar to the Eway_Rapid gateway in functionality.
+
+See the docblocks within the gateway classes for further information and links to the eWay gateway on
+line.
 
 For general usage instructions, please see the main [Omnipay](https://github.com/thephpleague/omnipay)
 repository.

+ * The eWAY Rapid gateways use an API Key and Password for authentication.
  *
- * There is also a test sandbox environment, which uses a separate endpoint and 
+ * Before gaining access to this connection type eWAY must be provided with proof
+ * of a PCI-DSS compliant environment with a current and valid PCI-DSS certificate.
+ * Note that transactions not involving credit card data (such as a recurring token

  * API key and password. To access the eWAY Sandbox requires an eWAY Partner account.
  * https://myeway.force.com/success/partner-registration
  *
- * Simple Purchase Example:
+ * If you're getting the response "Unauthorised API Access, Account Not PCI Certified"
+ * when testing with the sandbox, this means you're integrating Rapid Direct. If you're
+ * not using client side encryption then you will need to provide proof of PCI compliance
+ * when moving to the live endpoint.
+ *
+ * For testing in sandbox, it's a simple process to enable direct payments.
+ *
+ * * Log into your Sandbox Account
+ * * Hover the mouse over the Settings tab, then click on Sandbox.
+ * * Tick the box under Direct Payment Method (Next to PCI) and click on Save Sandbox Settings.
+ *
+ * You're now set up to test direct payments.
