Prerequisites

• Ruby 2.7+
• PStore (included in Ruby standard library — no extra install needed)

Getting Started

git clone https://github.com/lillysilly3/simple_note_app
cd simple_note_app
ruby main.rb

Project Structure

• main.rb - Entry point
• application.rb - Main application loop
• menu.rb - User interaction and menu actions
• manager.rb - Business logic layer
• database.rb - PStore persistence layer
• note.rb - Note model

What I Explored

• Object-oriented Ruby design with classes and modules
• Separating concerns across model, database, and application layers
• Persisting data with Ruby's built-in PStore
• Input validation and error handling
