 ### Meshtasticd Configuration
 
 - The meshtasticd configuration is at `/etc/meshtasticd/config.yaml` by default. If a `config.yaml` is found in the current directory, that takes precedence. And a config file specified with the `-c/--config` option has the highest precedence.
 
-To enable a LoRa radio connected to your device, uncomment the appropriate lines in the config file, including the Module line. As an example, the Waveshare SX126X module would have a Lora section that looks like this:
+To enable a LoRa radio connected to your device, first locate it's configuration in the presets, then copy to `config.d`.
 
-```yaml
