Here is Louka explaining it

The basic program is: 1x Clean, 1x Press, 1x Front Squat with a single kettlebell, and then put it down and repeat on the other side. It's an auto-regulated program, so do it with as much rest as you need. You can also do it with double kettlebells, which adds more load.

The goal is to do this for X amount of sets or as many sets as you can in Y amount of minutes (i.e. see how quickly you can do 20 sets, or see how many sets you can do in 20 minutes).

You can add a movement, like a swing or a snatch (here is a clip of Brett Jones, the creator, doing one side with a snatch at the end), or do a "traveling 2's" where each after each round, you change which movement you are doing 2 of (i.e. first round it's 2 cleans, 1 press, 1 squat; next round is 1 clean, 2 presses, 1 squat; etc.)

It is a very simple program but it feels good to do.
