 The igate.py receive data over the air from a serial attached data modem. This script is forwarding received APRS-Packets to APRS-IS (http://www.aprs-is.net/) and print receive to stdout.
 
+# Hardware Requierements
+
+* 2 Computers with Linux and Python 3 (Raspberry Pi zero work great)
+* 2 LoRa Data Radio Modems (tested with DRF1278DM from Dorji)
+* at least one UART to USB Adapter
+* if you use desktop and laptop and no Raspberry Pi you need three UART to USB adapters 
+
 You need at least two serial data modems like the Dorji DRF1278DM and two computers. For running tracker.py you need also a GPS module.

-Edit **config.txt** and enter your Callsign, APRS-IS passcode and serial interface. 
 
-This script is written for Python 3 and using **aprslib**. Please install this library with the following command.
+Install **aprslib** on both computers.

+## Setup APRS Tracker
+
+Setup the tracking Raspberry Pi is more complex. **tracker.py** is grabbing the data from gpsd. For running gpsd you need a GPS module which is connected to your computer. Please follow this guide for setting up GPS module on Raspberry Pi
+
+https://learn.adafruit.com/adafruit-ultimate-gps-hat-for-raspberry-pi/use-gpsd
+
+If you have everything setup correctly please use **cgps -s** to check gps location. Everything fine? The just start **tracking.py** and move around to do range testing of your LoRa-Modems
