+  RadioLib SX126x LR-FHSS Modem Example
+
+  This example shows how to use LR-FHSS modem in SX126x chips.
+  This modem can only transmit data, and is not able to receive.
+
+  NOTE: The sketch below is just a guide on how to use
+        LR-FHSS modem, so this code should not be run directly!
+        Instead, modify the other examples to use LR-FHSS
+        modem and use the appropriate configuration
+        methods.
+
+  For default module settings, see the wiki page
+  https://github.com/jgromes/RadioLib/wiki/Default-configuration#sx126x---lr-fhss-modem
+
+  For full API reference, see the GitHub Pages
+  https://jgromes.github.io/RadioLib/
