## What it is
Hello-CTF is a free, open-source CTF (Capture The Flag) beginner tutorial built with MkDocs Material and deployed at hello-ctf.com. It covers the five core CTF directions (MISC, Web, Crypto, Reverse, Pwn) plus extensions like AWD, AI, and Blockchain, with companion challenges, a competition calendar, tool guides, and CTF challenge authoring resources.

## Use cases
- learn CTF from zero as a complete beginner
- find a structured tutorial for web, crypto, reverse, pwn, and misc challenges
- set up a local CTF practice environment with deployable challenges
- track upcoming CTF competitions with a calendar feed
- learn how to author and containerize CTF challenges with Docker
- onboard new members of a CTF team or security club

## When to choose
- you are new to CTF or cybersecurity and want a free, beginner-friendly curriculum with hands-on challenges
- you mentor newcomers and need a reusable onboarding resource
- you want aggregated CTF event listings and tool references in one place

## When to avoid
- you need advanced, in-depth material on a single specialized exploitation topic
- you want an interactive hands-on platform rather than a documentation site (use its companion lab platforms instead)
- you need a certified or formal security training course

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: security, tutorials, education
- platform: python, self-hosted
- tags: ctf, capture-the-flag, cybersecurity, beginner-friendly, mkdocs, open-textbook, writeups, misc, web-security, cryptography, reverse-engineering, pwn, web-server, docker
