One of our Metasploit contributers, Brandon Perry, has put together a document detailing the recently released Penetration Testing Execution Standard (PTES) with the modules and functionality in the Framework. PTES is a push from a group of testers fed up with the lack of guidance and the disparate sources of basic penetration testing information. Brandon's document does a great job detailing disparate parts of the framework in the context of PTES.

Hopefully Brandon will continue to build this document out, as it is a handy resource. This helps make the PTES guidance actionable, and is a good read whether you're just getting started or you're an old hand with the framework.

Have a look at the document here.
