read the manual haha just kidding
i use winscp to upload all my install files, that way i don't have to mess with FTP / securities etc. chmod etc
just a note here to increase my security i have changed the port from 22 to something like 52919.
use winscp to copy the template folder (unzipped) into /joomlaint/tmp
then in your backend use "Extension Manager: Install"
"Install from Directory"
you will see something like
/home/e-smith/files/ibays/joomlaint/html/tmp
add "/templatefoldername"
and install
hope this helps.
