+# Log4OM Web Status
+
+This python program will take UDP messages blasted at it from Log4OM and will write it to a HTML file. It will
+continually update this file as messages come in. It requires you to let Log4OM automatically send status packets.
+
+### Usage
+
+Place the script on a system that can hear UDP from Log4OM and has a way of putting the resulting HTML file on a webserver
+as fast as possible.
+
+### Basic Operation
+
+Log4OM has a feature that has it send out UDP messages automatically as long as specific conditions are met. This python
+script/program will take in the messages sent at it's IP and parse a few things out of the XML. It writes this to an
+HTML file every time a message comes in; so the HTML generated is set to auto-reload every 5 seconds. It currently displays
+the following in a very basic way:
+
+- Your current VFO frequency and opearating mode.
+- Your TX offset/split if it exists
+
+If no data is received from Log4OM, because you turned your rig off or shutdown Log4OM; it will indicate your radio is
+off and wait for data to come back. Support is planned to show if rig is in transmit. 
+
+The "Radio Off" message happens after 15 seconds of no data. This is done by checking the elapsed time since the timestamo
+was last updated; which happens every time a message comes in.
