+# About
+This is a manual test application for the AT86RF2xx radio driver
+
+For running this test, you need to connect/configure the following pins of your
+radio device:
+- SPI MISO
+- SPI MOSI
+- SPI CLK
+- CS (ship select)
+- RESET
+- SLEEP
+- INT (external interrupt)
+
+# Usage
+For testing the radio driver you can use the netif and txtsnd shell commands
+that are included in this application.
