 script and some of its limitations.
 
 ## Introduction

+The screenshot is based on the DOM and as such may not be 100% accurate to the real representation
+as it does not make an actual screenshot, but builds the screenshot based on the information
 available on the page.
 
 ## How it works
 The script traverses through the DOM of the page it is loaded on. It gathers information on all the elements
 there, which it then uses to build a representation of the page. In other words, it does not actually take a
 screenshot of the page, but builds a representation of it based on the properties it reads from the DOM.

 elements on the page, which have been tainted with cross-origin content, they will become dirty and no longer readable by html2canvas.
