 ## Web Interface
 The Marquee Scroller uses the **WiFiManager** so when it can't find the last network it was connected to,
 it will become an **Access Point Hotspot** -- connect to it with your phone at http://192.168.4.1/ and you can then enter your WiFi connection information.
+This is shown on the LED display.
 
 After connected to your WiFi network it will display the IP address assigned to it and that can be
 used to open a browser to the Web Interface.  You will be able to manage your API Keys through the web interface.
