 ```javascript
 import XMLSerializer from '@teclone/xml-serializer';
 
-let instance = new XMLSerializer();

 The constructor can take a boolean argument that indicates if whitespace should be preserved in the serialized output. Default value is `true`;
 
 ```javascript
 // do not preserve white space
-let instance = new XMLSerializer(false);

 ### Using with [JSDOM](https://github.com/jsdom/jsdom)
 
-Currently, JSDOM has not implemented the `XMLSerializer` interface. This can be easily integrated with JSDOM and any other similar mockup environment or for web scrapping and xml feed parsing like below.

 ### Using on the browser
 
-The browser build is available inside the `dist` folder when you npm install the package. You can also this repo and run the build command locally. It exposes an `XMLSerializer` construct on the `window` object.

 Another improvement is that it removes all duplicate xml prefix definition on as recommended in the specification document unlike what web browsers do. Below is an example of
