## What it is
The official W3C repository developing the Web Content Accessibility Guidelines (WCAG) 2.x, including success criteria, definitions, Understanding documents, and techniques. It is a standards/specification source rather than runnable software, built with an Eleventy-based publishing pipeline.

## Use cases
- make my website accessible to people with disabilities
- check WCAG 2.2 success criteria for compliance
- learn how to meet accessibility requirements for web content
- find techniques for satisfying WCAG guidelines
- contribute to or track draft accessibility standards
- understand accessibility requirements for legal compliance like ADA or EN 301 549

## When to choose
- you need the authoritative, normative text of WCAG 2.x or its supporting Understanding and techniques documents
- you want to follow or contribute to the development of upcoming accessibility guidelines
- you need testable accessibility criteria to audit web content against

## When to avoid
- you want a tool that automatically scans or fixes accessibility issues in your site
- you need a linting or testing library to enforce accessibility in code
- you are looking for tutorials rather than the specification itself

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, accessibility
- domain: web-development, accessibility, documentation
- platform: cross-platform
