      Mountain Goat is your home for in-house bandit testing.
      
      We have installed your configuration file to config/mountain-goat.yml
      Please choose a password for each environment in this file.  Make
      sure this password is secure.
      
      This will copy necessary migrations to your db/migrate folder.  Please migrate
      your database before running mountain-goat.
      
      To access mountain-goat, navigate to /mg in your project.  Everything else
      should be handled by the gem.  Enjoy!
      
      1) Choose an admin-password in config/mountain-goat.yml
      2) Run `rake db:migrate`
      3) Start your server and navigate to 'http://mydomain.com/mg'
      4) Play around, read the docs, bandit, enjoy.
