Documentation is written directly in source code comments using /*doc */ blocks, keeping it synchronized with the code and reducing maintenance overhead.

Supports executable snippets like html_example and js_example that render interactively in the style guide, making components tangible and testable.

Users control the entire output with ERB templates for headers, footers, and code examples, allowing for brand-consistent and tailored style guides.

Custom code example renderers can be added for new languages, such as CoffeeScript, by defining them in the code_example_renderers folder.
