Wordpress help.

Hi mate, I'm a professional Wordpress developer.
The theme should have an 'auto import' option. This way you can import the content.

In wordpress under 'settings' you should find a content importer.
The theme should come with a file like 'demo-content.zip', you select this file and import it into wordpress.

After that your site should have all the demo / dummy content.

If that fails ask their support if they have demo content or see their user manual

Good luck mate
