Activating a demo version of a theme

Hi team,

Probably a bit of a silly question but I am a little new to this.

I am helping a friend upload a theme template which I have completed and the theme is running fine in wordpress.

newlifeconstructionsnt.com.au

I just didn’t want to spend lots of time in setting up the basic settings as I run my own company and am very busy. I was hoping there was a way to activate a demo version of the theme so then they have a base that they are happy with and they can then start inputting their content on their own?

I was hoping to activate Demo vs 5 in Wordpress if this is possible?

Depending on the item this should be doable either via XML or one-click in the theme admin.

If your friend logs in to the buyer account and downloads the documentation for the theme then this will almost certainly be covered on that
