 # string2js
 Create Javascript objects and primitives from their string representation
+
+This module expose a function to convert string values to Javascript objects. It
+also offer a `reviver()` function to be used with `JSON.parse()`.
+
+
+## RegExp
+
+The module allow to reviver `RegExp` objects. To serialize them automatically as
+JSON, just add the next snippet to the begining of your code:
+
+```js
+if(RegExp.prototype.toJSON === undefined)
+   RegExp.prototype.toJSON = RegExp.prototype.toString
+```
