## What it is
A community-maintained archive of guides, tools, and references for Capture The Flag (CTF) security competitions. It covers common CTF topics from beginner overviews to in-depth explanations of specific technologies and vulnerabilities.

## Use cases
- learn how to get started with ctf competitions
- find guides for solving ctf challenges
- look up tools for reverse engineering and web exploitation
- prepare for a capture the flag event
- teach beginners about computer security competitions
- find resources for specific ctf categories like crypto or pwn

## When to choose
- you are a beginner looking for a structured introduction to CTFs
- you want curated references and tool lists for common CTF topics
- you want a free, community-contributed knowledge base under CC0

## When to avoid
- you need an actual CTF platform or scoring server to host competitions
- you want hands-on challenges rather than documentation
- you need up-to-date coverage of the latest techniques, as the repo has not seen recent releases

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: security, reverse-engineering, penetration-testing, documentation
- domain: security, penetration-testing, education, tutorials
- platform: cross-platform
- tags: ctf, capture-the-flag, hacking, security-competition, beginner-guides, awesome-list
