Hello @issaaf,

Firstly, thank you very much for buying the pro version.

Actually, we do not have the demo file bundled within the theme but we do have the theme official documentation using which you can set up your site as in the demo:

Furthermore, if you find any confusion while setting up any of the section please write back to us.

Hope this helps.

Best Regards!!

Have a good day.
