 ### Creating Request JSON for Realex JS SDK
 
 ```php
-require_once ( 'vendor/autoload.php' );
+require_once 'vendor/autoload.php';
 
 use com\realexpayments\hpp\sdk\domain\HppRequest;
 use com\realexpayments\hpp\sdk\RealexHpp;

+	->addAccount( 'mySubAccount' )
+	->addAmount( '1001' )
+	->addCurrency( 'EUR' )
+	->addAutoSettleFlag( '1' );
 
 $supplementaryData = array();
 $supplementaryData['key1'] = 'value1';
 $supplementaryData['key2'] = 'value2';
 
 $hppRequest->addSupplementaryData( $supplementaryData );	
 
-$realexHpp = new RealexHpp( "mySecret" );
+$realexHpp = new RealexHpp( 'mySecret' );
 $requestJson = $realexHpp->requestToJson( $hppRequest );
 ```
 
 ### Consuming Response JSON from Realex Payments JS SDK
 
 ```php
-require_once ( 'vendor/autoload.php' );
+require_once 'vendor/autoload.php';
 
 use com\realexpayments\hpp\sdk\domain\HppResponse;
 use com\realexpayments\hpp\sdk\RealexHpp;

-$hppResponse = $realexHpp->responseFromJson( responseJson );
+$realexHpp = new RealexHpp( 'mySecret' );
+$hppResponse = $realexHpp->responseFromJson( $responseJson );
 ```
 ### HPP Select Stored Card

 $hppRequest = new HppRequest();
 $hppRequest
