Import the Demo Content
Log in to your WordPress dashboard and make sure you have activated your new theme before proceeding.
Within your WordPress Dashboard, navigate to Tools > Import, then choose “WordPress” from the list.
Click the "Choose File" button, then within theme package open "Demo Content" folder and select theme.xml file > click "Upload file and Import" button.
You will be asked to map the authors in this export file to users on the blog. For each author, you may choose to map to an existing user on the blog or to create a new user.
You will then have the choice to import attachments, so click on the “Download and import file attachments” box.
Please be patient while WordPress imports all the content.
This will import the demo site's images, posts, pages, etc. Please note that while the XML file can import the demo site's content, it cannot import the Customizer settings. You will then need to select your homepage layout, preferred colors, enable/disable sidebar, etc. within the theme's Customizer section.
