I want to have all the content like the demo site. How do I do that?

You can do that by importing the demo data from the provided XML file which is included in the full purchased package.

For a full guide of how to install the theme (and import the demo data), we would suggest reading through the theme documentation. There are also some useful tutorials provided in the doc to help you get started with the theme.

Note that the documentation is also included right in the purchased package. Just go to the 'Documentation' folder and open the 'index.html' file with your browser.
