The document discusses how to manage multiple LoRa gateways connected to The Things Network (TTN) using balena.io. It outlines steps to set up a Raspberry Pi-based gateway running the BasicStation software and connect it to TTN. These include creating a balena.io account, deploying the BasicStation software, flashing an SD card, and registering the gateway on TTN. Managing gateways this way allows for continuous integration and remote access to logs, similar to how software developers work with code.
