The Team menu option on the left is where you add team members. To add a new client, select the Team > Add New option from the left hand WordPress menu. You will then be able to provide an image for the team member, and various info if you’d like through the team meta box, see the image on the right.

To display your team members, you will then need to create a page that includes the “Team” page builder asset. This asset features various options for you to change the way the team members are displayed.
