 <h1>WB8WFK ARDF Foxoring Transmitter</h1>
 <p>This is a simple, inexpensive, transmitter controller for conducting ARDF Foxoring competitions and for demonstrating ARDF principles. The software project is an Arduino script that builds for and runs on most Arduino-like products, including <a href="https://www.adafruit.com/product/2590">AdaFruit's Metro Mini 328</a>, or <a href="https://www.sparkfun.com/products/11113">SparkFun's Arduino Pro Mini 328</a>, and many more.</p>
 
+<p>Controller support for all the common ARDF competition formats is provided: Classic, Sprint, and Foxoring.
+
 <h2>Software</h2>
 <p>The software is a proper Arduino script that will open and build without warnings or errors in Arduino IDE version 1.8.12 and later. The Arduino IDE can also be used to program a device that holds a compatible bootloader. Most Arduino products ship with a bootloader pre-installed.</p>
