+  RadioLib RTTY Transmit AFSK Example
+
+  This example sends RTTY message using SX1278's
+  FSK modem. The data is modulated as AFSK.
+
+  Other modules that can be used for RTTY:
+  - SX127x/RFM9x
+  - RF69
+  - SX1231
+  - CC1101
+  - Si443x/RFM2x
+  - SX126x/LLCC68
+
+  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/
