+# MCP Documentation Guidelines
+
+## Build Commands

+
+## Style Guidelines
+- Follow existing MDX formatting and components
+- Keep content clear, concise, and technically accurate
+- Include practical code examples where appropriate
+- Test all links and code samples before submitting
+- Maintain consistent structure with existing documentation
+- When documenting CLI commands, use two-line format with the prompt on a separate line: `$ claude` followed by `> /command`
+- Use appropriate headings: "When to use", "Steps", and "Tips" for tutorials
+- Branch naming convention: prefix with "ashwin/" (e.g., "ashwin/add-mcp-cli-docs")
+
+## File Organization
+- Place new pages in appropriate sections (concepts, tutorials, etc.)
+- Update docs.json when adding new pages
+- Follow existing file naming conventions (kebab-case.mdx)
+- Include proper frontmatter in MDX files
+
+## Documentation Standards
+- Prioritize user understanding over technical completeness
+- Document both basic syntax and concrete examples
+- Structure command documentation with clear formatting
+- For image analysis examples, use quotes: `$ claude "Analyze this image: /path/to/image.png"`
