+HTTP CONSOLE
+============
+New as of Jan. 2018, the OP25 dashboard is accessible to any Web browser over
+HTTP.  Include the option "-l http:<host>:<port>" when starting the rx.py app,
+where <host> is either "127.0.0.1" to limit access from only this host, or
+"0.0.0.0" if HTTP access from anywhere is to be allowed*.  After rx.py has
+started it begins listening on the specified port for incoming connections.
+
+Once connected the status page should automatically update to show trunking
+system status, frequency list, adjacent sites, and other data.
+
+Example:  you have started rx.py with the option "-l http:127.0.0.1:8080".
+To connect, set your web browser URL to "http://127.0.0.1:8080".
+
+If one or more plot modes has been selected using the "-P" option you may
+view them by clicking the "PLOT" button.  The plots are updated approx.
+every five seconds.  Click "STATUS" to return to the main status page.
+
+*WARNING*: there is no security or encryption.  Be careful when using "0.0.0.0"
+as the listening address since anyone with access to the network can connect.
+
+NOTE: the python-pyramid package is required when using this option.   It can
+be installed by running
+     sudo apt-get install python-pyramid
