### generate new app, skipping Test::Unit file generation

````rails new my_app -T````

### Set up Gemfile
source 'http://rubygems.org'

gem 'rails', '3.1.0'

gem 'sqlite3'
gem 'simple_form'
gem 'thin'
gem 'heroku'
gem 'paperclip'
gem 'activeadmin'
gem 'devise'
gem 'cancan'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails', "  ~> 3.1.0"
  gem 'coffee-rails', "~> 3.1.0"
  gem 'uglifier'
end

gem 'jquery-rails'

group :test do
  gem 'database_cleaner'
  gem 'rails3-generators' #mainly for factory_girl & simple_form at this point
  gem 'rspec-rails'
  gem 'factory_girl_rails'
  gem 'cucumber-rails'
  gem 'capybara'
end

group :development do
  gem 'awesome_print', :require => 'ap'
end

````
bundle install
````


### Configure generators to use the gems we want, and skip view spec generation

````ruby
# in config/application.rb

config.generators do |g|
  g.test_framework :rspec, :views => false, :fixture => true
  g.fixture_replacement :factory_girl, :dir => 'spec/factories'
  g.form_builder :simple_form
end
````

### turn on autoloading of lib directory and all its subdirectories

In Rails 3+, the lib directory is no longer autoloaded.

````ruby
# in config/application.rb
config.autoload_paths += %W(#{config.root}/lib)
config.autoload_paths += Dir["#{config.root}/lib/**/"]
````

### run install tasks for our gems

````
rails g cucumber:install
rails g rspec:install
rails g active_admin:install
rails g simple_form:install
````
