If you're reading this, then thank you for purchasing a Duckbutt! These Duckbutt SAOs are built to be simple to configure using basic software. The first thing you will need to do is download the Arduino IDE.
The Arduino IDE will do almost everything you need out of the box, however we will need to get the ATtiny85 board package installed in order to send our payloads to the Vidar. To do this, open the Arduino IDE and click Arduino (or File in Windows) > Preferences... and then in the "Additional Boards Manager URLs" section, and add 'https://raw.githubusercontent.com/ArminJo/DigistumpArduino/master/package_digistump_index.json' to the list. (Huge thanks to @LambdaCalculus7 for finding this updated Digistump board configuration!)
