The DIY (Do It Yourself) module allows you to enter custom code into a module position, with this you can easily add embeddable widgets such as the facebook like box.
There is very few options in the backend of the module, simply enter your code and choose an aligntment (left, centre, right).
Add in your code
As you can see I now have the facebook like button on the right hand module position.
