+# code-doc-cli
+
+A CLI tool that automatically extracts documentation from code comments, function signatures, and type annotations to generate clean Markdown documentation. Supports Python, TypeScript, and Go with CI/CD integration capabilities.
+
+## Features
+
+- Multi-language Support: Parse Python, TypeScript, and Go source files
+- Smart Comment Detection: Extract Google-style, JSDoc, and GoDoc comments
+- Markdown Generation: Create well-structured documentation with syntax highlighting
+- CI/CD Integration: Exit codes and flags for pipeline integration
+- Configuration File: Customize behavior with `code-doc.toml`
+- JSON Output: Machine-readable output for tooling integration
+

+```
+
+Generate documentation for an entire project:
+
+```bash
+code-doc generate /path/to/project
+```
+
+Generate documentation and save to a file:
+
+```bash
+code-doc generate -o docs/API.md /path/to/project
