How to prepare for a Hackathon with IBM Cloud?

Today I want to address a common situation for developers: You want to participate in a hackathon, and you plan to use IBM Cloud, but you have never used it before. How to prepare? My motivation to write this: I will support the hacknext hackathon from 7-9 March 2019 in Munich as a coach. (
