installation of PDF invoice

[radvla]

I download a set of files intended to generate amd mail PDF invoice, they are plugin,componenet for invoices and two independent files for msil snd pdf generation.

Th e first question I have it is how to install them. IF i hvae just to unzip in the joomla extenson mamanger or more thnigs are necessary.

There is any tutorial in video for this install and initiate the first works with this extensions?

Thanks
