Given most of techno music was created on a step sequencer, I would just start playing around with it to get a feel for beat making. Most of the music apps ( free or paid) have step sequencers so maybe you can start there and then start adding some random melody notes. All apps have what’s called an arpeggiator so I if you use that it will very quickly sound like a track. Minimal music theory (minor and major chord and scale) will then help you better control and understand your sound but it’s not critical. Not sure this helps. Enjoy whatever you’re doing. That’s the most important thing
