-Enter following commands:<br/>
-```

-## Configuration
-Afterwards configure as following:
-### Edit aprx/aprx.conf.lora-aprs file
-Type:
-```
-cd
-cd RPi-LoRa-KISS-TNC
-sudo cp aprx/aprx.conf.lora-aprs /etc/aprx.conf
-pico -w /etc/aprx.conf
-```
-to copy and then open the config file.
-
-The most important settings are:
-* **mycall**<br/>
-Your call with an apropriate SSID suffix<br/>[Paper on SSID's from aprs.org](http://www.aprs.org/aprs11/SSIDs.txt) 
-* **myloc**<br/>
-NMEA lat/lon form:
-```
-lat ddmm.mmN lon dddmm.mmE
-```
-Example:
-```
-lat 4812.52N lon 01622.39E
-```
-(simplest way to find the right coordinats for this? Go to [aprs.fi](http://www.aprs.fi) on your location right-click and choose "Add marker" then click on the marker and you should see your coordinates in the NMEA style - enter this infos without any symbols into the config file as seen in the example above)

 # Raspberry Pi LoRa KISS TNC
 
-This project emulates a KISS TNC and controls a hardware LoRa transceiver
-connected to the Raspberry´s SPI. That makes it possible to use existing
-software, like digipeaters, with LoRa radio communication. The KISS TNC is
-accessed via its TCP server.
-
-The current application is to run the KISS TNC together with the APRS digi [APRX](https://github.com/PhirePhly/aprx), which connects via TCP and provides
-powerful APRS digipeating and I-gate functionality for LoRa-APRS.
+This project was originally started by Tom Kottek (https://github.com/tomelec/RPi-LoRa-KISS-TNC). Because the program had some problems dealing with digipeated frames (it crashed when receiving a ssid with the 'has_been_digipeated' flag -*- set), I took on the task of fixing the code for my personal use.
 
 ## Hardware
 
-The LoRa KISS TNC runs on Raspberry Pi 2 or newer together with the
-*LoRa APRS Gateway Hat V2.0*. However, RFM98W oder RFM96W LoRa modules can
-be wired up to the Raspberry Pi directly aswell. See the
-[schematic](doc/LoRaAPRS-GW-RPI_V20_Schematic.pdf) for details.
-
-![Gateway on RPi](doc/images/LoRa-APRS_Gateway_V20.jpg)
+I also designed my own (open source) hardware for it: a board holding a Raspberry Pi Zero 2 W, an SX1278 LoRa transceiver and a power supply with on/off button to safely switch on and off the system. The design files can be found on my website: [RPi LoRa_shield](https://meezenest.nl/mees/RPi_LoRa_shield.html)
 
-## Development
+## Software
 
-This program and documentation is in a very early state and very experimental.
-Only the LoRa radio modem of the gateway board is supported at the moment.
-Display and buttons are not working.
+The software controls the LoRa transceiver connected to the Raspberry´s SPI bus and emulates a KISS TNC over TCP. That makes it possible to use existing software like APRX. It is also possible to attach the KISS interface to the AX.25 stack via socat/kissattach.
 
 ### To Do
-* Python 3 compatibility
-* Get display and buttons working
-* Noise floor telemetry
-* Installation guide and documentation
-* Proper configuration file
-* ...
+* A lot
