FightCrew

Hi!

I downloaded the latest version: 0.9.5, 2016/03/26.

Going to the Sigil Home page, it is said:
-------------
Don’t forget the FlightCrew plugin
Please note, the epub2 validator FlightCrew has been converted to a plugin for Sigil 0.8.900 and later.
This plugin has been updated for Sigil-0.9.3 (and later). It can be downloaded from the official Sigil-Ebook flightcrew repository if you have not already installed it.
-------------

OK, I downloaded it and unzipped it.

Now how I do use it, where to place the files and folders corresponding to my Windows 7/64?

Thanks in advance, regards,
