This plugin should only be used on Genesis sites (on non-Genesis sites, it won’t break anything, but it also won’t do anything at all other than setting up the post type).

If you take a look at the tutorial above, you’ll see the basics of what this plugin does. In addition to setting up the staff-member post type and staff-position taxonomy, this plugin automatically sets up a thickbox lightbox which lets you show content about each staff member in a popup when the featured image is clicked.
