# Help URL Reference

Centralized mapping of accessibility rule IDs and WCAG criteria to external help documentation. Used by CSV reporters, audit report generators, and any agent that links findings to remediation guidance.

## Accessibility Insights (Web Accessibility)

### axe-core Rule URL Pattern

```text
Base URL: https://accessibilityinsights.io/info-examples/web/
Pattern:  {base_url}{rule-id}
Example:  https://accessibilityinsights.io/info-examples/web/image-alt/
```

For any axe-core rule, construct the URL by appending the rule ID to the base URL. This pattern covers all axe-core rules.
