The last step after installation the Theme, plugins and importing the demo data is to setup your home page and menu, that  can help you to get your new Theme setup and ready for you to edit as you want.

At first, to set your Front Page you should head to Settings > Reading.

Although, by default WP is set to show your latest posts, to make your Theme just like our demo you should choose a static front page from the pages provided in the demo data.
