 See the Wiki Software Install page for more details: https://github.com/alanbjohnston/CubeSatSim/wiki/Software-Install. To build and run the software on a Raspberry Pi 3B, 3B+, or Pi Zero W:
+Requires:
+- Raspbian Stretch or Buster, full desktop or Lite 
+- wiringpi
+- git
+- libasound2-dev
+- pi-power-button
+- Direwolf
+- rpitx
+
+See the Wiki Software Install page for more details: https://github.com/alanbjohnston/CubeSatSim/wiki/Software-Install. To build and run the software on a Raspberry Pi 3B, 3B+, or Pi Zero W (Does NOT work on a Pi 4 since rpitx does not work on it yet):
+
+`sudo apt-get install -y wiringpi git libasound2-dev i2c-tools`
+
+Run raspi-config and enable the I2C bus by selecting Option 5 Interfacing Options and then Option 5 I2C and selecting Y to enable the ARM I2C bus:
+
+`sudo raspi-config`
+
+Select Finish at the bottom to exit raspi-config. Then type:
+
+`sudo cp /boot/config.txt /bootconfig.txt.0`
+
+`sudo nano /boot/config.txt`
+
+Use the down arrow key to go down in the file until you find this line:
+
+`# Additional overlays and parameters are documented /boot/overlays/README `
+
+Add the following two lines under it:
+
+`dtoverlay=i2c-gpio`
+
+`dtparam=i2c_vc=on`
+
+Press Ctrl-X then type `y` then hit Enter to save the file and exit the editor. You should back at the pi@... prompt. Reboot by typing:
+
+`sudo reboot`
+
+after logging back into the Pi, type:
+
+`ls -a /dev/i2c*`
+
+you should see three I2C buses:
+
+`i2c-0 i2c-1  i2c-3`
+
+Continue the install by typing:
+
+`cd`
+
+Then type:
 
 `git clone http://github.com/alanbjohnston/CubeSatSim.git`
 
 `cd CubeSatSim`
 
-Edit the afsk/main.c file to set your amateur radio callsign, then 
+`git checkout fox-v4`
+
+Edited the sim.cfg file to set your amateur radio callsign, then 
 
 `make rebuild`
 
-To hear AFSK telemetry (X.25 data), your radio or SDR to 434.9 MHz FM, and you should receive telemetry from the CubeSat Sim:
+`git clone https://www.github.com/wb2osz/direwolf`
+
+`cd direwolf`
+
+`make -j`
+
+(takes a while)
+
+`sudo make install`
+
+`make install-rpi`
+
+Note that this last command may fail if you are using Raspbian Lite since there is no Desktop.
+
+`cd ~/CubeSatSim`
+
+`git clone https://github.com/F5OEO/rpitx.git`
+
+`cd rpitx`
+
+`./install.sh`
+
+(Takes a while).  It will prompt you if you want to modify /boot/config.txt file.  Type a `y` and the script will complete.
+
+`cd ~/CubeSatSim`
+
+`git clone https://github.com/Howchoo/pi-power-button.git`
+
+`cd pi-power-button`
+
+`cp ../python/listen-for-shutdown.py listen-for-shutdown.py`
+
+`./script/install`
+
+To make the demo.sh script run automatically on boot:
+
+`sudo cp /CubeSatSim/systemd/cubesatsim.service /etc/systemd/system/cubesatsim.service`
+
+`sudo systemctl enable cubesatsim`
+
+Now reboot for all the changes to take effect:
+
+`sudo reboot now`
+
+After rebooting, to hear AFSK telemetry (X.25 data), tune your radio or SDR to 434.9 MHz FM, and you should receive telemetry from the CubeSat Sim:
 
-`./radioafsk`
 
 This code uses the Brandenburg Tech Digital Transceiver, based on DigitalTxRxRP  https://brandenburgtech.wordpress.com/ If you don't have the SPI Interface enabled and the board plugged in, you will get an error.
