Just found a x4 penis extender, first time using it, where can I find a tutorial on putting it together/etc?

As title states, just found my x4 extender I had bought a while ago I forgot about, I decided I am going to start using it.. Only problem is I don't know how to properly use it. There is a CD in the box but my computer does not have a CD player (Mac OS).. It is this one, X4 Labs Extender System Review 2022

Anyone have any advice on where I can find videos or tutorials on how to attach this so I can start using it? thank you so much, any replies are greatly appreciated!
