This document discusses deploying a Ruby on Rails application to Heroku. It covers the key steps of deployment including packaging the application with Bundler, using Git for updates, and scaling the application on Heroku dynos. Local deployment is discussed first for development using Pow and Foreman for scaling locally. Remote deployment on Heroku is then covered, highlighting how Heroku provides easy deployment to their PaaS with automatic scaling based on usage.
