To Add a Logo to Your Mini-Website

You'll need to hit "Save" at the bottom of the page for a link of your logo .png or .jpeg file to appear:
About Us and Policies & Procedures sections
Beneath the logo option discussed above are two text boxes for you to add some custom text to your page. See the text in the red boxes below:

If you do not want the Policies & Procedures text to display, uncheck the box in the middle of the page:
