+- **Content Format**: Markdown files with frontmatter support
+- **Link Validation**: Automated via `make testlink` and GitHub Actions
+
+### Development Workflow
+
+1. Content changes: Edit markdown files in appropriate directories
+2. Navigation changes: Update `.vitepress/config.ts`
+3. Test locally with `yarn dev`
+4. Validate links with `make testlink`
+5. Create PR - preview deployment will be available
+6. Merge to main triggers automatic deployment
+
+### Important Conventions
+
+- Use relative links for internal documentation references
+- Place images in `/public/img/`
+- Blog posts should include proper frontmatter with date and author
+- Guides should be structured with clear step-by-step instructions
+- Technical documentation in `/learn` should be comprehensive and accurate
