Origin
How this came to be.
Two teams. A few hackathons. One shared document that kept getting better.

The Good Boys
The team that started it.
Ralf Boltshauser, Samuel Baumgartner, Marco Pagano, and Lionel Ding started competing at hackathons together. They kept placing well. At Start Hack, ETH AI Hack, BaselHack, Moin Hack. After each event they wrote down what had worked and what hadn't.
Over time that document became their operating system. The principles, the field rules, the checklists. The first version of this guidebook.
At Start Hack they met Konrad and his team. They shared the guidebook. Konrad's team used it and won their next hackathon. They came back with things the guide had missed.

Konrad and the team
The team that made it better.
Konrad te Heesen, Lukas Strickler, Marco Ginaneschi, and Franz Dieter added their own experiences and perspectives. A few things the original guide had missed. A few things only a different team would notice.
That is how an internal document from one team became something worth sharing publicly.
