The document discusses deploying a Rails application to Amazon EC2. It explains that the goals are to launch an EC2 instance, connect to it, set up the environment, deploy the application, and profit. It then outlines the plan to launch an instance, connect to it, install necessary packages like Ruby, Rails, and Nginx, configure Nginx and Unicorn, deploy the application using Capistrano, and start the Unicorn process.
