At the bottom on the left hand side of any of the posts by AXBMCUSER <the creator> is a link to install the repository and then install the skin from that repository.
As for the "download" part - Technically all addons must be downloaded whether from inside of kodi or not.
To access the repository that contains the skin you have to tell kodi where it is so you must "download " the repository link before you can install the skin from inside kodi.
hope that answers your question.

Thanks. I downloaded zip and put it in a folder on kodi. Then I tried install from zip but nothing happens, like if the zip was empty. But its not.
I have installed from repos many times so I know who to do it. But this does not work.

ok, not to dispute that nothing is happening for you, but i just tried it again and it worked fine for me.
just trying to figure it out, when you try to install the repository.zip the box doesn't show up indicating that the repository was added?
Do you get the warning that it is dangerous to install third party zips?
Check the name and file size compared to what i have to make sure it is not corrupted.
Name repository.axbmcuser.zip size 18.8kb 19353bytes
 Simple suggestions would be to make sure that install third party zips is allowed, and maybe move the file to another location and try from there. check permissions on the file, and then retry downloading if you haven't already.
not sure what else can be done.

Thanks. I changed to another folder and it worked.
