+   RadioLib APRS Position Example
+
+   This example sends APRS position reports 
+   using SX1278's FSK modem. The data is
+   modulated as AFSK at 1200 baud using Bell 
+   202 tones.
+
+   DO NOT transmit in APRS bands unless
+   you have a ham radio license!
+
+   Other modules that can be used for APRS:
+    - SX127x/RFM9x
+    - RF69
+    - SX1231
+    - CC1101
+    - nRF24
+    - Si443x/RFM2x
+
+   For default module settings, see the wiki page
+   https://github.com/jgromes/RadioLib/wiki/Default-configuration
+
+   For full API reference, see the GitHub Pages
+   https://jgromes.github.io/RadioLib/
