+Canvas2Svg
 ==========
+This library turns your Canvas into SVG using javascript. In other words, this library lets you build an SVG document using the canvas api. Why use it?
+* You have a canvas drawing you want to persist as an SVG file.
+* You like exporting things.
+* Because you didn't want to transform your custom file format to SVG.
+
+Demo
+==========
+http://gliffy.github.io/canvas2svg/
+
+How it works
+==========
+We create a mock 2d canvas context. Use the canvas context like you would on a normal canvas. As you call methods, we build up a scene graph in SVG. Yay!
+
+Usage
+==========
+```javascript
+//Create a new mock canvas context. Pass in your desired width and height for your svg document.
+var ctx = new C2S(500,500);
+
+//draw your canvas like you would normally
+ctx.fillStyle="red";
+ctx.fillRect(100,100,100,100);
+//etc...
+
+//serialize your SVG
+var mySerializedSVG = ctx.toString(); //true here, if you need to convert named to numbered entities.
+
+//If you really need to you can access the shadow inline SVG created by calling:
+var svg = ctx.__root;
+```
+
+Misc
+==========
+Some canvas 2d context methods are not implemented yet. Watch out for setTransform and arcTo.
