-Back in your project:
+Then run this generator with an optional IP address to copy over a deploy.rb that is more suited to this gem.
+The application name defaults to the same name as your rails app and the repository is pulled from your .git/config.

+    rails g cap_bootstrap:install 99.99.99.99

+Double check the settings in config/deploy.rb and then run:
 
     cap deploy:install
     cap deploy:setup
     cap deploy:cold
 
 ## Advanced Options
 
+Shown below are the default advanced settings, but they can overridden.

+Example:
+    rails generate cap_bootstrap 255.255.255.255
