demo homepages and purchase code

Hi guys,

First time working with this topic, but I have worked with other topics of themefores team. I need some information about how to install the theme homepages demonstration. Could you please help me to do it? I remember that there is an example of data importer in Zeyn theme, right? Can i do it the same way in Boutique Theme?

I need also some help to set up my purchase code. Could you please help me on this?
