The theme comes with "One Click Demo Import" feature and importing demo data (post, pages, images, theme settings, ...) is the easiest way to setup your theme. It will allow you to quickly edit everything instead of creating content from scratch.
After you install all the required plugins you can navigate to Appearance > Import Demo Data.
Choose your desired layout and click the button "Import". The import process will start and this process may take a while on some hosts, so please be patient.
Once the import is done, the success notice will appear in the center of your screen.
Note: The Demo Importer works best to import on a new fresh install of WordPress. If you're not using a fresh install, make sure you backup your current theme options as they will be overwritten.
