How to use LoRa-E5 with Arduinos

Thanks for your answer! Euhm yeah I would like to connect them by P2P.
In fact, to be precise, I need 4 transmitter and one receiver.
You says that it’s easy but do you know where I can find some documentation or tuto because I can find a good and simple tuto for LoRa-E5.

Thank you for your help
