This plugin ads some extra options to your Customizer (like social icons), registers taxonomies and custom posts types for: 
– Portfolio items 
– Testimonials 
– FAQ 
– Team Members
This plugin doesn’t change how new post types are displayed in your theme. e.g You’ll need to add templates for archive-portfolio.php and single-portfolio.php if you want to customize the display of portfolio items.
