## What it is
A community-driven style guide for Ruby on Rails covering routing, controllers, models, migrations, views, and more. It serves as the reference for the RuboCop Rails cops and documents recommended coding conventions.

## Use cases
- how should I structure Rails routes
- best practices for ActiveRecord models
- Rails coding conventions for teams
- style rules for Rails migrations
- how to write skinny controllers in Rails
- recommended Rails style guide for RuboCop

## When to choose
- you write Ruby on Rails code and want consistent team conventions
- you use RuboCop Rails and want to understand the rationale behind its cops
- you are onboarding developers to a Rails codebase

## When to avoid
- you need executable linting rather than documentation (use rubocop-rails)
- you work outside Ruby or Rails
- you need a machine-readable config rather than prose guidance

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation
- domain: web-development, developer-tools, documentation
- platform: cross-platform
- tags: ruby, rails, style-guide, rubocop, code-style, best-practices
