-This is very much a work-in-progress, with much to be completed. For now, the following works:
+## Configuration & Startup
+Many settings are defined in horusmapper.cfg configuration file.
+Create a copy of the example config file using
+```
+$ cp horusmapper.cfg.example horusmapper.cfg
+```
+Edit this file with your preferred text editor. The config file contains descriptions of each setting.
 
-To listen for payload data from OziMux (i.e. on UDP:localhost:8942):
+You can then start-up the horusmapper server with:
 ```
-$ python chasemapper.py --ozimux
-```
-
-To listen for payload data via the UDP broadcast 'Payload Summary' messages (which can be generated by OziMux, but also by [radiosonde_auto_rx](https://github.com/projecthorus/radiosonde_auto_rx/)):
-```
-$ python chasemapper.py --summary
+$ python horusmapper.py
 ```
 
 The server can be stopped with CTRL+C.
 
 
 ## Live Predictions
-kml_server can also run live predictions of the flight path. 
+We can also run live predictions of the flight path. 
 
 To do this you need cusf_predictor_wrapper and it's dependencies installed. Refer to the [documentation on how to install this](https://github.com/darksidelemm/cusf_predictor_wrapper/).
+
 Once compiled and installed, you will need to: 
  * Copy the 'pred' binary into this directory. If using the Windows build, this will be `pred.exe`; under Linux/OSX, just `pred`.
  * [Download wind data](https://github.com/darksidelemm/cusf_predictor_wrapper/#3-getting-wind-data) for your area of interest, and place the .dat files into the gfs subdirectory. 
 
-TODO: Update below doc. Most settings are set from the web interface.
-
-The following additional arguments can then be used:
-
-```
-  --predict             Enable Flight Path Predictions.
-  --predict_binary PREDICT_BINARY
-                        Location of the CUSF predictor binary. Defaut = ./pred
-  --burst_alt BURST_ALT
-                        Expected Burst Altitude (m). Default = 30000
-  --descent_rate DESCENT_RATE
-                        Expected Descent Rate (m/s, positive value). Default =
-                        5.0
-  --abort               Enable 'Abort' Predictions.
-  --predict_rate PREDICT_RATE
-                        Run predictions every X seconds. Default = 15 seconds.
-```
-
-For example, to use kml_server to observe a typical radiosonde launch (using data emitted via the [payload summary messages](https://github.com/projecthorus/radiosonde_auto_rx/wiki/Configuration-Settings#payload-summary-output)), you would run:
-```
-$ python chasemapper.py --summary --predict --burst_alt=26000 --descent_rate=7.0
-```
-
-
-A few notes:
- * The ascent rate is calculated automatically, and is an average of the last 6 positions.
- * The 'Abort' prediction option is used to display a second prediction, which displays what would occur if the balloon burst *now*. This is useful for flights where you have a cutdown payload available, and want to know when to trigger it! This prediction disappears when the payload is either above the expected burst altitude, or is descending.
