title: Bare minimum configuration needed to deploy an app with capistrano?
body: <p>Is this the bare minimum amount of options needed to deploy an application stored in a repo on my local development machine? </p>
  
  <pre><code># config/deploy.rb
  set :scm, "git" # is this necessary?
  set :user, "deployer"  # is this the username of my vps? How do I set the password?
  set :deploy_to, "/rails_apps" # will this install the app to the /deployer/rails_apps directory of my ubuntu vps?
  </code></pre>
  
  <p>I still don't know how to specify the ip of my vps, or the password.</p>
  
  <p>I've noticed that the config file is huge..why would I need to specify any more options than this? What more would I possibly want to do once the app is online?</p>
