+Using with node.js
+==================
+
+You can use `canvas2svg` with node.js using [jsdom](https://github.com/tmpvar/jsdom) with [node-canvas](https://github.com/Automattic/node-canvas). To do this first create a new document object, and then create a new instance of `C2S` based on that document:
+
+```javascript
+var canvas = require('canvas'),
+    jsdom = require('jsdom'),
+    C2S = require('canvas2svg');
+
+var document = jsdom.jsdom();
+var ctx = new C2S({document: document});
+
+// ... drawing code goes here ...
+```
+
+N.B. You may not need node-canvas for some simple operations when using jsdom >= 6.3.0, but it's still recommended that you install it.
