Once the plugin is activated, a new button will be available inside the editor, press the "rounded cross" button to access the shortcode generator. A new window will appear from which you can select the shortcode that you want to add. After selecting a shortcode new options will be available, each option comes with a short description underneath the label that explains what to do and how to use it.
