+## 📝 Documentation Standards
+
+### Writing New Documentation
+
+1. **Use templates** from `specs/` for consistency
+2. **Include code examples** that are tested and work
+3. **Add cross-references** to related documentation
+4. **Keep it updated** when making code changes
+5. **Follow markdown linting** rules (see `.markdownlint.json`)
+
+### Documentation Structure
+
+Each major doc should include:
+- **Overview** - What is this about?
+- **Quick Start** - How do I use it?
+- **Configuration** - How do I configure it?
+- **Examples** - Show me working code
+- **Troubleshooting** - What if it doesn't work?
+- **Related Docs** - Where can I learn more?
+
+### Maintenance
+
+- User guides: Update when user-facing features change
+- Developer guides: Update when APIs or architecture change
+- Feature docs: Update when feature capabilities change
+- Architecture docs: Update when design decisions change
