## What it is
A community-maintained archive of CTF (capture the flag) write-ups and challenge source files, organized by year from 2013 to 2017. It centralizes solutions that would otherwise be scattered across personal blogs and often lost.

## Use cases
- find write-ups for a past CTF competition
- learn how to solve capture the flag challenges
- study security challenges as a beginner
- recover original challenge files for a CTF
- contribute my own CTF solution write-up

## When to choose
- you need solutions or challenge files from CTFs held in 2013-2017
- you want complete, community-reviewed explanations suitable for newcomers
- you want a permanent archive that won't disappear like personal blogs

## When to avoid
- you need write-ups for CTFs after 2017, as this archive is no longer updated
- you want an interactive CTF practice platform rather than written solutions
- you need a tool or library rather than a reference collection

## Facets
- artifact type: dataset
- maturity: maintenance
- function: documentation, security
- domain: security, education, tutorials
- platform: cross-platform
- tags: ctf, write-ups, capture-the-flag, community-maintained, archive
