Wonderblog theme comes with "One Click Demo Import" feature which allows you to import all the demo posts, pages, images, theme settings, etc. This is the easiest way to setup your theme and it will allows 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.
Click the blue button "Import Demo Data" and the import process will start. 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.
