Beginner's question: Parameters for registering end device for Adafruit Feather M0 with RFM95 LoRa Radio

OK, thank you.
I took this decision following Beginner: Raspberry PI SX162 SX1302 Gateway - #6 by descartes

Does this then mean that I have to look for what I am missing in the GitHub LMIC Node library? (will this library provide them?)
