  Hackathons and similar time-bounded events have become a global phenomenon.
Their proliferation in various domains and their usefulness for a variety of
goals has subsequently led to the emergence of different formats. While there
are a multitude of guidelines available on how to prepare and run a hackathon,
most of them focus on a particular format that was created for a specific
purpose within a domain for a certain type of participants. This makes it
difficult in particular for novice organizers to decide how to run an event
that fits their needs. To address this gap we developed a planning kit that is
organized around 12 key decision that organizers need to make when preparing
and running a hackathon, and the tradeoffs that drive decision-making. The main
planning kit is available online while this report is meant as a downloadable
and citable resource.
