+## Changing the Web Server Port.
+     
+If your Pi already has a web server on port 80, you can reconfigure PiPedal to use a different port. After installing PiPedal, run the following command on your Raspberry Pi:
+     
+     sudo pipedalconfig --install --port 81
+     
+You can optionally restrict the addresses on which PiPedal will respond by providing an explicit IP address. For example, to configure PiPedal to only accept connections from the local host:
+     
+     sudo pipedalconfig --install --port 127.0.0.1:80
+     
+To configure PiPedal to only accept connections on the Wi-Fi host access point:
+     
+     sudo pipedalconfig --install --port 172.22.1.1:80
