+# ruby-things
+
+A collection of Ruby learning exercises, koans, and small projects designed to explore core language features, object-oriented programming, blocks, and testing idioms.
+
+## Description
+
+This repository serves as a practical playground for mastering Ruby. It contains:
+- **Ko`koans/`**: Self-paced exercises covering arrays, hashes, blocks, inheritance, exceptions, and control statements.
+- **`test/`**: Minitest suites for validating implementations of arrays, classes, blocks, hashes, and utility scripts.
+- **`player/`**: A modular music player implementing `Song`, `Playlist`, and `UniquePlaylist` classes with corresponding tests.
+- **Learning Scripts**: Standalone examples (`blocks.rb`, `classes-1.rb` through `classes-10.rb`, `catch.rb`) demonstrating Ruby syntax, closures, accessors, visibility, and `catch/throw` mechanics.
+
+## Installation
+
+Requirements:
+- Ruby 2.5+ or Ruby 3.x
+- `minitest` gem
+
+Install dependencies and clone the repository:
+```bash
+git clone https://github.com/zmack/ruby-things.git
+cd ruby-things
+gem install minitest
+```
+
+## Usage
+
+### Running Tests
+All test files are written in Minitest and can be executed directly with Ruby:
+```bash
+ruby test/array_test.rb
+ruby test/basic_blocks.rb
+ruby test/classes_test.rb
+ruby test/test_deps.rb
+```
+
+### Exploring Koans
+The koans directory contains interactive learning exercises. Run them individually or use the provided autotest script:
+```bash
+ruby koans/about_asserts.rb
+ruby koans/about_arrays.rb
+# Run via autotest (requires autotest gem)
+ruby koans/autotest/rubykoan.rb
+```
+
+### Executing Learning Scripts
+Run the standalone Ruby scripts to observe features in action:
+```bash
+ruby blocks.rb
+ruby classes-10.rb
+ruby catch.rb
+```
+
+### Player Module
+The `player` module can be loaded directly or its tests can be run:
+```bash
+ruby player/test/playlist_test.rb
+ruby player/test/song_test.rb
+ruby player/test/unique_playlist_test.rb
+```
