The book is currently broken down into several sections and is intended to be read sequentially. Getting started will show how to install and get started with Ruby in your environment. Basic Ruby demonstrates the main features of the language syntax. The Ruby language section is organized like a reference to the language. Available modules covers some of the standard library. Intermediate Ruby covers a selection of slightly more advanced topics. Each section is designed to be self contained. The book is a work in progress and is subject to change.
