4. Theme Options
The theme uses the WordPress Customizer feature for it's global/theme options. Customizer is a native WordPress feature which was added in WordPress back in 2012, so if you've ever used WordPress you won't have any problems.
Note: Only functionality related options are in the Customizer. For styling options use Meridian Styler, more on that further down the documentation.
You can access the customizer at WP Admin → Appearance → Customize. In there you will see these sections:
In the general section of the theme options you can set the logo image, both regular and for retina displays and the image that displays as the background.
In the social section of the theme options you can set the URLs to your social website profiles. They will be used in the social widget.
In the footer section of the theme options you can enable/disable differents footer elements and also change the copyright text.
