## What it is
A collection of Ruby code examples demonstrating classic software design patterns such as Adapter, Builder, Command, Decorator, Factory, Observer, Singleton, and Strategy. It serves as a reference for learning how Gang of Four patterns are implemented idiomatically in Ruby.

## Use cases
- learn how to implement design patterns in Ruby
- see a working example of the adapter pattern
- understand the difference between builder and factory patterns
- find a Ruby example of the observer pattern
- study singleton and strategy pattern implementations
- reference for teaching design patterns

## When to choose
- you are learning or teaching classic design patterns with Ruby examples
- you want concise, runnable code snippets for each GoF pattern
- you need a quick reference while refactoring Ruby code toward known patterns

## When to avoid
- you need a production-ready pattern library or gem to depend on
- you work in a language other than Ruby
- you need actively maintained or officially licensed material (no license is provided)

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: developer-tools, tutorials, programming-languages
- platform: ruby
- tags: design-patterns, ruby, code-examples, gang-of-four, educational
