How are the icons for twitter and facebook ect showing?
When I try this my icons are just white circles?

Hi, add this in your code:

     <link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css"

How would I change one of those icons to something of my own? I wanted to put a telephone as one for calls.

Try in this site https://fontawesome.com/v4.7.0/icons/, search your preference icon.
