Capistrano is a server automation and deployment tool. It makes a whole bunch of servers simultaneously perform actions. This could be deploying our application, or clearing their cache. Capistrano tells each of our servers to pull the latest branch from Git, perform any necessary build steps, and deploy the application on itself. Setting up this process is what we'll be detailing.
