Jekyll theme install

Good morning all

I’m looking to install a jekyll theme and especially this one :

I followed the instructions on the internet but I don’t quite understand how to install it, jekyll is to install on vps under ubuntu 18.04.

Thanks in advance for the help provided

Nobody can help me ?

why are you installing jekyll on the vps? you can just upload the _site folder there.

As far as i can tell that theme is something you need to download all the files and add them to your site. Normally if I do this I download the entire repo, remove the demo site and then add in my files.
