 ## Usage
 
     var sass = require('node-sass');
+    sass.render(scss_content, callback [, options]);
+
+Especially, the options argument is optional. It support two attribute: `include_paths` and `output_style`, both of them are optional.
+
+`include_paths` is an `Array`, you can add a sass import path.
+
+`output_style` is a `String`, its value should be one of `'nested', 'expanded', 'compact', 'compressed'`.
+[Important: currently the argument `output_style` has some problem which may cause the output css becomes nothing because of the libsass, so you should not use it now!]
+
+Here is an example:
+
+    var sass = require('node-sass');
     sass.render('body{background:blue; a{color:black;}}', function(err, css){
       console.log(css)
-    });
+    }/*, { include_paths: [ 'lib/', 'mod/' ], output_style: 'compressed' }*/);
