+# Design System Audit Documentation
+
+## Overview
+
+This directory contains comprehensive documentation for auditing design system compliance across all components in the Frontend Recipeer application. The audit framework ensures consistency, accessibility, and maintainability of our atomic design-based component system.
+
+## Quick Start
+
+1. **Review the [Audit Criteria](./audit-criteria.md)** to understand evaluation standards
+2. **Familiarize yourself with the [Scoring Methodology](./scoring-methodology.md)** for consistent evaluation
+3. **Download the [Component Tracking Template](./component-audit-template.csv)** to track audit progress
+4. **Use the [Audit Report Template](./audit-report-template.md)** to document findings
+5. **Reference the [Accessibility Checklist](./accessibility-checklist.md)** for WCAG 2.1 AA compliance
+

+## Audit Framework
+
+### Evaluation Areas (100 points total)
+
+1. **Design Token Compliance** (25 points)
+   - Color usage and theme integration
+   - Typography scale adherence
+   - Spacing consistency
+
+2. **Visual Consistency** (25 points)
+   - Component variants and states
+   - Layout patterns and responsive design
+   - Visual hierarchy
+
+3. **Accessibility Compliance** (25 points)
+   - WCAG 2.1 AA requirements
+   - Keyboard navigation and screen reader support
+   - Interactive accessibility
+
+4. **Theme Support** (15 points)
+   - Light/dark mode adaptation
+   - System theme detection
+
+5. **Documentation Quality** (10 points)
+   - Storybook documentation completeness
+   - Code documentation and examples
+
+### Component Priority Levels
+
+- **Critical (90+ score required)**: Foundational atoms (Button, Input, Typography)
+- **High (80+ score required)**: Key molecules and organisms (QuantityAdjuster, RecipeCard)
+- **Medium (70+ score required)**: Complex organisms and templates
+- **Low (60+ score required)**: Experimental or legacy components
+
+## Audit Process
+
+### 1. Planning Phase
+- [ ] Identify components for audit using priority levels
+- [ ] Assign auditors and schedule audit dates
+- [ ] Set up tracking system using component template
+
+### 2. Evaluation Phase
+- [ ] Score components using detailed criteria
+- [ ] Document findings with evidence
+- [ ] Identify issues and improvement opportunities
+
+### 3. Reporting Phase
+- [ ] Complete audit reports using standard template
+- [ ] Prioritize issues by severity
+- [ ] Create actionable improvement plans
+
+### 4. Remediation Phase
+- [ ] Address critical and major issues
+- [ ] Re-audit improved components
+- [ ] Update tracking system with results
+
+### 5. Continuous Improvement
+- [ ] Schedule regular re-audits
+- [ ] Update criteria based on learnings
+- [ ] Share best practices across team
+
+## Getting Started with Audits
+
+### For New Auditors
+
+1. **Read the documentation**: Start with audit criteria and scoring methodology
+2. **Review the example audit**: Study the [Button component audit example](./example-button-audit.md) to understand the process
+3. **Practice scoring**: Audit a simple atom component to understand the process
+4. **Shadow experienced auditor**: Observe an audit session for complex components
+5. **Start with low-risk audits**: Begin with non-critical components
+
+### For Component Developers
+
+1. **Understand the criteria**: Review audit standards before building components
+2. **Use the accessibility checklist**: Ensure WCAG compliance during development
+3. **Test across themes**: Verify light/dark mode support
+4. **Document thoroughly**: Create comprehensive Storybook stories
+5. **Self-audit before submission**: Use the criteria to review your own work
+
+## Tools and Resources
+
+### Required Tools
+- **Storybook**: Component documentation and visual testing
+- **Browser DevTools**: Accessibility and contrast checking
+- **axe DevTools**: Automated accessibility testing
+- **Screen reader software**: Manual accessibility testing
+
+### Recommended Tools
+- **WAVE**: Web accessibility evaluation
+- **Lighthouse**: Performance and accessibility auditing
+- **Color contrast analyzers**: Ensuring WCAG compliance
+- **Figma**: Design comparison and measurement
+
+### Learning Resources
+- [WCAG 2.1 Guidelines](https://www.w3.org/WAI/WCAG21/Understanding/)
+- [Atomic Design Methodology](https://atomicdesign.bradfrost.com/)
+- [Tailwind CSS Documentation](https://tailwindcss.com/docs)
+- [WAI-ARIA Authoring Practices](https://www.w3.org/WAI/ARIA/apg/)
+
+## Quality Assurance
+
+### Audit Consistency
+- Multiple auditors should review high-priority components
+- Regular calibration sessions to maintain scoring consistency
+- Cross-validation of audit results for critical components
+
+### Continuous Improvement
