Install Extras Modules

I installed ansible using apt on ubuntu. I want to use win_say module which is an extras module. Can anyone guide me on how to install ???

The extras get installed with the normal package, but win_say is new in 2.3 which has not been released yet, so it might not be available for the version you installed.

You can always try downloading the module and putting it in a library/ dir adjacent to play or inside role.
