kOS is a very fun rabbithole, the language can strange at first, it's a reactive paradigm with a special flow. I started with the [PID tutorial](https://ksp-kos.github.io/KOS/tutorials/pidloops.html https://ksp-kos.github.io/KOS/tutorials/pidloops.html) to learn PID in a fun environnent. Then programming orbital maneuvers to dig into orbital mechanics. The community is really active, with a lot of challenges like spaceX booster landing.
