+  RadioLib LR11x0 GNSS Autonomous Position Example
+
+  This example performs GNSS scans and calculates
+  position of the device using autonomous mode.
+  In this mode, scan data does not need to be uploaded
+  to LoRaCloud, however, it requires up-to-date almanac
+  data. Run the LR11x0_Almanac_Update example to update
+  the device almanac.
+
+  NOTE: This example will only work for LR11x0 devices
+        with sufficiently recent firmware!
+        LR1110: 4.1
+        LR1120: 2.1
+        If your device firmware reports older firmware,
+        update it using the LR11x0_Firmware_Update example.
+
+  For full API reference, see the GitHub Pages
+  https://jgromes.github.io/RadioLib/
