Google domain name and a Squarespace Template

Site URL: http://www.simpleclearhelpful.com.au

I think I am happy I have found Squarespace.

I have registered my domain name and like a Squarespace template.

I want to know can I use the image how do I publish the template?

I guess the rest like is it easy to edit the template and publish it to my domain name will come later.
