+  RadioLib LoRaWAN End Device APB Example
+
+  This example sets up a LoRaWAN node using APB (activation
+  by personalization). Before you start, you will have to
+  register your device at https://www.thethingsnetwork.org/
+  After your device is registered, you can run this example.
+  The device will start uploading data directly,
+  without having to join the network.
+
+  NOTE: LoRaWAN requires storing some parameters persistently!
+        RadioLib does this by using EEPROM, by default
+        starting at address 0 and using 32 bytes.
+        If you already use EEPROM in your application,
+        you will have to either avoid this range, or change it
+        by setting a different start address by changing the value of
+        RADIOLIB_HAL_PERSISTENT_STORAGE_BASE macro, either
+        during build or in src/BuildOpt.h.
+
+  For default module settings, see the wiki page
+  https://github.com/jgromes/RadioLib/wiki/Default-configuration
+
+  For full API reference, see the GitHub Pages
