You don't have to install the site shaper, that is just an option if you want all the demo data. You can just install the template by itself.
Thanks for the reply. I've just looked at your video to install Site Shaper, but it runs through it far too quickly for me. If I decided to install Site Shaper and came across issues, would I be able to come back to Shape 5 for help? I'm hosting with SiteGround and I'm not sure if they will help if I screw up the installation.
