Beginner needs help - dual max14870 motor driver shield with Arduino Uno

Hi I would need maybe a lot of help. I'm a beginner to electronic coding and I don't know where to start at all.
I would need to know; how to code an arduino uno with the dual max14870(to control 2 dc motors from an external source( step sequencer ))→ how and where to wire a mono jack cable with its positive and negative wires(for each dc motors) and would need to know probably more about other things too that i haven't even figured out yet...

Search for "arduino uno + max14870".
Search for "arduino + "external source(?)"".

You do that and if it doesn't work You're wellcome to ask for help.
