This document discusses RubyGems and the process for creating and publishing a Ruby gem. It explains that a gem is a packaged Ruby application or library with a name and version. It then provides steps for building a gem using different tools like Bundler, Jeweler, and Hoe+Echoe. It also outlines the process of building, installing and publishing a gem to RubyGems.org including using a Rubygems API key in the credentials file.
