-- Semantic: GRC program requirements (SOC 2, GDPR, etc.) parsed, structured, and rendered with Markdown
-- Linkable: Map similar controls from different frameworks with a custom control framework
-- Practical: Minimal, risk-focused control framework (24 controls) tailored for modern organizations
+## What is this?
+
+A practical, minimal control framework (24 controls) tailored for modern AWS SaaS organizations. Focuses on risk-reducing behaviors over checkbox compliance, with bidirectional mappings to SOC 2 and GDPR requirements.
+
+**Key features:**
+- **Semantic:** GRC requirements (SOC 2, GDPR) parsed, structured, and rendered as navigable Markdown
+- **Linked:** Bidirectional mappings show how controls satisfy multiple framework requirements
+- **Practical:** Implementation guidance for real-world AWS SaaS environments (~100 people, macOS endpoints, cloud-native)
 
 ## Published Documentation
 
-The published example uses a custom control framework (24 controls) tailored for AWS SaaS organizations with ~100 people and macOS endpoints. Focuses on risk-reducing behaviors over checkbox compliance.
