+REST API SDK for PHP  (V0.5.0)
+==============================
+
+	PayPal's PHP SDK for the RESTful APIs
+
+
+Prerequisites
+-------------
+
+   * PHP 5.3 or above
+   * curl, json & openssl extensions must be enabled
+   * composer for running the sample out of the box (See http://getcomposer.org)
+
+
+Running the sample
+------------------
+
+   * Ensure that you have composer installed on your machine.
+   * Navigate to the samples folder and run 'composer update'.
+   * Optionally, update the sdk_config.ini file with your own client Id and client secret.
+   * Run any of the command line samples in the folder to see what the APIs can do.
+    
+    
+Usage
+-----
+
+To write an app that uses the SDK 
+
+   * Copy the composer.json file from the sample folder over to your project and run 'composer update' to fetch all 
+dependencies
+   * Copy the sample configuration file sdk_config.ini to a location of your choice and let the SDK know your config path using the following define directive
+    
+       define('PP_SDK_CONFIG_PATH', /path/to/your/sdk_config.ini);
+    
+   * Obtain your clientId and client secret from the developer portal and add them to your config file	
+   * Now you are all set to make your first API call. Create a resource object as per your need and call the relevant operation or invoke one of the static methods on your resource class.
+    
+    $payment = new Payment();
+
+    $payment->setIntent("Sale");
+
+    ...
+    
+    $payment->create();
+    
+      *OR*
+    
+    $payment = Payment::get('payment_id');    
+    
+    These examples pick the client id / secret automatically from your config file. You can also set API credentials dynamically. See the sample code for how you can do this.

+Rest API Samples
+===================
+
+
+This sample project is a simple web app that you can explore to understand what the payment APIs can do for you. To try out the sample, run `composer update` from the samples folder and you are all set.
+
+
+The sample comes pre-configured with a test account but in case you need to try them against your account, you must
+   
+   * Obtain your client id and client secret from the developer portal
+   * Update the sdk_config.ini file with your new client id and secret.
+   
+   
+If you are looking for a full fledged application that uses the new RESTful APIs, check out the Pizza store sample app at https://github.com/paypal/rest-api-sample-app-php
