Adding your TeamUp widget to a WordPress powered website is extremely simple.
First, navigate to the page editor for the page where you want the widget to appear. Select the "Text" tab to enter "Text Mode," which will allow you to paste in HTML directly.
Then simply paste the widget code you copied from the Customer Site page on TeamUp.
