WPBadgeDisplay is a WordPress plugin for displaying Open Badges on your blog.
Download the WPBadgeDisplay plugin, moving the WPBadger folder into the /wp-content/plugins/ directory on your server, and install it like any other WordPress plugin.
Add the badge widget to your theme by navigating to Appearance -> Widgets in the WordPress administrative panel. There, you can specify where you'd like to display badges (for example, your theme's main sidebar).
Configure the widget by adding the email address badges are associated with, and adding an optional title that will display above your badges.
