-### Running tests ###
-
-The library has two sets of tests. The first set is a number of qunit tests that check that different values parsed by browsers are correctly converted in html2canvas. To run these tests with grunt you'll need [phantomjs](http://phantomjs.org/).
-
-The other set of tests run Firefox, Chrome and Internet Explorer with [webdriver](https://github.com/niklasvh/webdriver.js). The selenium standalone server (runs on Java) is required for these tests and can be downloaded from [here](http://code.google.com/p/selenium/downloads/list). They capture an actual screenshot from the test pages and compare the image to the screenshot created by html2canvas and calculate the percentage differences. These tests generally aren't expected to provide 100% matches, but while committing changes, these should generally not go decrease from the baseline values.

+nextUrl: "/getting-started"
+nextTitle: "Getting Started"
+---
+
+Before you get started with the script, there are a few things that are good to know regarding the 
+script and some of its limitations.
+
+## Introduction
+The script allows you to take "screenshots" of webpages or parts of it, directly on the users browser.
+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.
+            
+            
+As a result, it is only able to render correctly properties that it understands, meaning there are many 
+CSS properties which do not work. For a full list of supported CSS properties, check out the 
+[supported features](/features/) page.
+
+## Limitations
+All the images that the script uses need to reside under the [same origin](http://en.wikipedia.org/wiki/Same_origin_policy) 
+for it to be able to read them without the assistance of a [proxy](/proxy/). Similarly, if you have other `canvas` 
+elements on the page, which have been tainted with cross-origin content, they will become dirty and no longer readable by html2canvas.
+
+The script doesn't render plugin content such as Flash or Java applets.
+
+## Browser compatibility
+
+The library should work fine on the following browsers (with `Promise` polyfill):
+ - Firefox 3.5+
+ - Google Chrome
+ - Opera 12+
+ - IE9+
+ - Edge
+ - Safari 6+

+---
+title: "FAQ"
+description: "Explore Frequently Asked Questions regarding html2canvas"
+---
+
+## Why aren't my images rendered?
+html2canvas does not get around content policy restrictions set by your browser. Drawing images that reside outside of 
+the [origin](https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy) of the current page [taint the 
+canvas](https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_enabled_image#What_is_a_tainted_canvas) that they are drawn upon. If the canvas gets tainted, it cannot be read anymore. As such, html2canvas implements 
+methods to check whether an image would taint the canvas before applying it. If you have set the `allowTaint` 
+[option](/configuration) to `false`, it will not draw the image.
+
+If you wish to load images that reside outside of your pages origin, you can use a [proxy](/proxy) to load the images.
+
+## Why is the produced canvas empty or cuts off half way through?
+Make sure that `canvas` element doesn't hit [browser limitations](https://stackoverflow.com/questions/6081483/maximum-size-of-a-canvas-element) for the `canvas` size or use the window configuration options to set a custom window size based on the `canvas` element:
+```
+await html2canvas(element, {
+    windowWidth: element.scrollWidth,
+    windowHeight: element.scrollHeight
+});
+```
+The window limitations vary by browser, operating system and system hardware.
+
+### Chrome
+> Maximum height/width: 32,767 pixels
+> Maximum area: 268,435,456 pixels (e.g., 16,384 x 16,384)
+
+### Firefox
+> Maximum height/width: 32,767 pixels
+> Maximum area: 472,907,776 pixels (e.g., 22,528 x 20,992)
+
+### Internet Explorer
+> Maximum height/width: 8,192 pixels
+> Maximum area: N/A
+
+### iOS
+> The maximum size for a canvas element is 3 megapixels for devices with less than 256 MB RAM and 5 megapixels for devices with greater or equal than 256 MB RAM
+
+## Why doesn't CSS property X render correctly or only partially?
+As each CSS property needs to be manually coded to render correctly, html2canvas will *never* have full CSS support. 
+The library tries to support the most [commonly used CSS properties](/features) to the extent that it can. If some CSS property 
+is missing or incomplete and you feel that it should be part of the library, create test cases for it and a new issue for it.
+
+## How do I get html2canvas to work in a browser extension?
+You shouldn't use html2canvas in a browser extension. Most browsers have native support for capturing screenshots from 
+tabs within extensions. Relevant information for [Chrome](https://developer.chrome.com/extensions/tabs#method-captureVisibleTab) and 
+[Firefox](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D#drawWindow()).

+html2canvas does not get around content policy restrictions set by your browser. Drawing images that reside outside of 
+the origin of the current page taint the canvas that they are drawn upon. If the canvas gets tainted, 
+it cannot be read anymore. If you wish to load images that reside outside of your pages origin, you can use a proxy to load the images.
