## What it is
A collection of Cookpad's coding style guides covering Ruby, Objective-C, Swift, Android Java, CoffeeScript, and Python, written in Japanese and English. It defines MUST and SHOULD conventions used to guide code reviews and development practices.

## Use cases
- adopt a company-wide ruby style guide
- coding conventions for swift and objective-c teams
- reference for code review style rules
- python coding standards document
- android java style guidelines
- bilingual japanese english style guide

## When to choose
- your team wants battle-tested style conventions from a large production engineering org
- you need Japanese-language coding standards
- you want a baseline to adapt for Ruby, Swift, or Python code reviews

## When to avoid
- you need an enforceable linter or formatter config rather than prose guidelines
- you want machine-readable or auto-fixable style rules
- you need guides for languages not covered here

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, linter, formatter
- domain: developer-tools, programming-languages, documentation
- platform: cross-platform
