RadioHead zip file

I have looked on the site below so that I could use a RadioHead library file in Arduino so that I could use data radios:

and found the following information:

Install in the usual way: unzip the distribution zip file to the libraries sub-folder of your sketchbook

It's probably pretty obvious to others but where are the zip file/s located for installation in the Arduino library? all I could find were .h files

Open that RadioHead page. Start reading from the top. The third sentence is this : The version of the package that this documentation refers to can be downloaded from That is the zip file.
(No Github, no download button, no special effects, just a link in a sentence :wink: )

Thanks Koepel,

I was looking in the files section for this file - my brain hurts!
