I see that many sites are using the same template of documentation:

[PrettyFaces](http://ocpsoft.com/docs/prettyfaces/snapshot/en-US/html/GettingStarted.html)
[Hibernate](http://docs.jboss.org/hibernate/stable/core/reference/en/html/tutorial.html)

and more.

Is it a template that I can download somewhere? It's so clear!
