+Introduction
+============
+canvg is a SVG parser and renderer. It takes a URL to a SVG file or the text of an SVG file, parses it in JavaScript, and renders the result on a [Canvas](http://dev.w3.org/html5/2dcontext/) element.  The rendering speed of the examples is about as fast as native SVG.
+
+What's implemented?
+===================
+The end goal is everything from the [SVG spec](http://www.w3.org/TR/SVG/). The majority of the rendering and animation is working.  If you would like to see a feature implemented, don't hesitate to contact me or add it to the issues list.
+
+Potential uses
+===============
+* Allows for inline embedding of SVG through JavaScript (w/o having to request another file or break validation)
+* Allows for single SVG version across all browsers that support Canvas
+* Allows for mobile devices supporting Canvas but not SVG to render SVG
+* Allows for SVG -> Canvas -> png transition all on the client side (through [toDataUrl](http://www.w3.org/TR/html5/the-canvas-element.html#dom-canvas-todataurl))
+
+Example Demonstration
+=====================
+[view here](http://gabelerner.github.io/canvg/examples/index.htm)
+Tested in Chrome, Firefox, Opera, and IE (through FlashCanvas)
+
+[jsfiddle playground](http://jsfiddle.net/qDmhV/)
+
+Usage
+=====
+Include the following files in your page:
+```html
+<script type="text/javascript" src="http://gabelerner.github.io/canvg/rgbcolor.js"></script> 
+<script type="text/javascript" src="http://gabelerner.github.io/canvg/StackBlur.js"></script>
+<script type="text/javascript" src="http://gabelerner.github.io/canvg/canvg.js"></script> 
+```
+
+Put a canvas on your page
+```html
+<canvas id="canvas" width="1000px" height="600px"></canvas> 
+```
+
+Example canvg calls:
+```html
+<script type="text/javascript">
+window.onload = function() {
+  //load '../path/to/your.svg' in the canvas with id = 'canvas'
+  canvg('canvas', '../path/to/your.svg')
+
+  //load a svg snippet in the canvas with id = 'drawingArea'
+  canvg(document.getElementById('drawingArea'), '<svg>...</svg>')
+
+  //ignore mouse events and animation
+  canvg('canvas', 'file.svg', { ignoreMouse: true, ignoreAnimation: true }) 
+}
+</script>
+```
+
+The third parameter is options:
+* log: true => console.log information
+* ignoreMouse: true => ignore mouse events
+* ignoreAnimation: true => ignore animations
+* ignoreDimensions: true => does not try to resize canvas
+* ignoreClear: true => does not clear canvas
+* offsetX: int => draws at a x offset
+* offsetY: int => draws at a y offset
+* scaleWidth: int => scales horizontally to width
+* scaleHeight: int => scales vertically to height
+* renderCallback: function => will call the function after the first render is completed
+* forceRedraw: function => will call the function on every frame, if it returns true, will redraw
+* useCORS: true => will attempt to use CORS on images to not taint canvas
+
+You can call canvg without parameters to replace all svg images on a page. See the [example](http://gabelerner.github.io/canvg/examples/convert.htm).
+
+There is also a built in extension method to the canvas context to draw svgs similar to the way [drawImage](http://www.w3.org/TR/2dcontext/#dom-context-2d-drawimage) works:
+```javascript
+var c = document.getElementById('canvas');
+var ctx = c.getContext('2d');
+ctx.drawSvg(SVG_XML_OR_PATH_TO_SVG, dx, dy, dw, dh);
+```
