-## Extensions
-### jQuery
-If you prefer jQuery style, you can add following code to add a jQuery extension.
-
-Code
-```JavaScript
-jQuery.md4 = md4
-```
-And then you could use like this:
-```JavaScript
-$.md4('message');
-```
-### Prototype
-If you prefer prototype style, you can add following code to add a prototype extension.
-
-Code
-```JavaScript
-String.prototype.md4 = function() {
-  return md4(this);
-};
-```
-And then you could use like this:
-```JavaScript
-'message'.md4();
-```
