## What it is
A community-driven Ruby coding style guide published as a website (rubystyle.guide), covering layout, naming, idioms, and language usage conventions. It serves as the reference standard that the RuboCop linter enforces.

## Use cases
- how should I format Ruby code
- Ruby naming conventions for methods and classes
- should I use tabs or spaces in Ruby
- Ruby best practices for conditionals and loops
- style rules enforced by RuboCop
- community Ruby coding standards

## When to choose
- you want an authoritative, community-accepted reference for Ruby code style
- you are configuring or interpreting RuboCop cop behavior
- you are onboarding Ruby developers to a shared style standard

## When to avoid
- you need an executable linter or formatter rather than a document (use RuboCop itself)
- your team already has its own style guide that diverges from community norms

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, linter, developer-tools
- domain: developer-tools, programming-languages, documentation
- platform: cross-platform
- tags: ruby, style-guide, coding-standards, rubocop, best-practices, code-style
