## What it is
arc42 is an open-source template for documenting and communicating software architecture, structured into twelve well-defined sections. It is technology- and process-agnostic, available in multiple formats (AsciiDoc, Markdown, Word) and 12 languages.

## Use cases
- document software architecture
- structure architecture documentation for a team
- communicate system design to stakeholders
- create architecture docs in AsciiDoc or Markdown
- prepare for iSAQB architecture certification
- standardize architecture documentation across projects

## When to choose
- you need a proven, pragmatic structure for architecture documentation
- your team wants low-effort docs that stay up to date
- you want a technology- and process-agnostic template usable in agile or formal settings

## When to avoid
- you need tooling that auto-generates documentation from code
- you require a strict formal notation like UML-only documentation
- your organization mandates a different documentation standard such as C4 or ISO 42010 templates

## Facets
- artifact type: learning-resource
- maturity: stable
- function: documentation, markdown, developer-tools
- domain: documentation, developer-tools, web-development
- platform: cross-platform, cli
- tags: architecture-documentation, asciidoc, template, software-architecture, isaqb
