This repository serves as a reference guide and checklist for attending events, particularly the Chaos Communication Congress (CCC) series. It consists of three main markdown files: a comprehensive attendee checklist (README.md), a directory of communication channels for CCC events (CCCongress Info Channels.md), and emergency information for a specific event (39C3 Emergency Info.md). The content is organized to help participants prepare for, navigate, and follow up after events, covering topics from packing lists and safety procedures to communication methods and post-event activities. While primarily documentation rather than software, it functions as an active tool that users consult and update via pull requests.
