Shortcodes
Shortcodes are the main way to add functionality to a site using this plugin. For most use cases, adding shortcodes will be all you have to do to setup a new site. Shortcodes may be used in any theme via the do_shortcode() function.
Dashboard
All plugin options are configurable by the WordPress dashboard under the single category ‘Payments’.
