In normal source installs Metasploit Framework comes with a docs/ folder located under the root of where Metasploit Framework is installed. I along with my fellow Metasploit developers have been trying to push some of the documentation for Metasploit into this folder so that people can build the documentation locally and so that it is more easily accessible to users.

However I have noticed that this folder is not distributed with the Kali Linux version of Metasploit. Instead I see other folders like db/ and documentation/, but not the docs/ folder I was looking for.
