-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.
