 ### Options
 
-#### options.separator
-Type: `String`
-Default value: `',  '`
+#### options.visitors
+Type: `Array`
+Default value: `[]`
 
-A string value that is used to do something with whatever.
-
-#### options.punctuation
-Type: `String`
-Default value: `'.'`
-
-A string value that is used to do something else with whatever else.
+A list of visitors to apply when transpiling.
 
 ### Usage Examples
 
 #### Default Options
-In this example, the default options are used to do something with whatever. So if the `testing` file has the content `Testing` and the `123` file had the content `1 2 3`, the generated result would be `Testing, 1 2 3.`
-
-```js
-grunt.initConfig({
-  jstransform: {
-    options: {},
-    files: {
-      'dest/default_options': ['src/testing', 'src/123'],
-    },
-  },
-});
-```
-
-#### Custom Options
-In this example, custom options are used to do something else with whatever else. So if the `testing` file has the content `Testing` and the `123` file had the content `1 2 3`, the generated result in this case would be `Testing: 1 2 3 !!!`
+In this example, the javascript written in ES6 will transpile classes, arrow funciton, and object short notation down to ES5 code.
 
 ```js
 grunt.initConfig({
   jstransform: {
     options: {
-      separator: ': ',
-      punctuation: ' !!!',
+      visitors: ['class', 'arrow-function', 'object-short-notation']
     },
     files: {
-      'dest/default_options': ['src/testing', 'src/123'],
+      'dest/app.js': ['src/app.js']
     },
-  },
+  }
 });
 ```
 
+This plugin supports all visitors exposed by [jstransform](https://github.com/facebook/jstransform) which are:
+
+- class (declaration, expressions, extends, method, super)
+- arrow functions
+- object short notation
+- rest params
+- templates
+
