+Setting the configurations
+----------
+```php
+use PHPZxing\PHPZxingDecoder;
+
+$config = array(
+    'try_harder' => true, // Non mobile mode
+    'multiple_bar_codes' => true, // If the image contains muliple bar codes
+    'crop' => '100,200,300,300', // If you want to crop image in pixels
+);
+$decoder        = new PHPZxingDecoder($config);
+$decodedData    = $decoder->decode('../images/'); // Reads images in complete directory
+print_r($decodedData);
+```
+
+You can also use it with configurations. The Decoder has 3 configurations,
+
+| Config Name           | Function                                                       |
+| -------------         |--------------------------------------------------------------|
+| try_harder            | If the image has bar/Qr code at unknown locations, then use this non mobile mode. |
+| multiple_bar_codes    | If the image has multiple bar codes you want to read. |
+| crop                  | Crop the image and it will read only the cropped portion |
+
+More Examples
+----------
+
+You can pass array of images too,
+
+```php
+use PHPZxing\PHPZxingDecoder;
+
+$decoder        = new PHPZxingDecoder();
+// Images can be sent as an array
+$imageArrays = array(
+    '../images/Code128Barcode.jpg',
+    '../images/Code39Barcode.jpg'
+);
+$decodedData    = $decoder->decode($imageArrays);
+print_r($decodedData);
+```
+
+Set Java Path
+----------
+If your java PATH is not set properly, the decoder will not work. You need to set path of java variable.
+
+```php
+use PHPZxing\PHPZxingDecoder;
+
+$decoder        = new PHPZxingDecoder();
+**$decoder->setJavaPath('/your/path/to/java');**
+$decodedData    = $decoder->decode('../images/Code128Barcode.jpg');
+print_r($decodedData);
+```
+
+Where is my java located ?
+----------
+If you do not know the path to java, then you can use the following on *nix enviromnents
+```
+$ which java
