Install Packet Forwarder in Raspberry Pi 3 B+

Hello,

I am trying to set up LoRa using a Raspberry Pi 3 B+. I am not using the Gateway OS Full image provided by Chirpstack, as I need to have the freedom to install any other needed application in the Raspberry.

I have followed the guides o the webpage to install the Network Server, the Application Server and the Gateway Bridge, and they are all running. However, I did not find any instructions to install the Packet Forwarder. How can I install it so that it can be running with the iC880A module?

Thank you.
