 Get the gem into either your gemspec or your Gemfile, depending on how you manage your engine's dependencies:
 
 ```ruby
 # gemspec
-gem.add_development_dependency 'combustion', '~> 0.5.4'
+gem.add_development_dependency 'combustion', '~> 0.5.5'
 
 # Gemfile
-gem 'combustion', '~> 0.5.4', :group => :test
+gem 'combustion', '~> 0.5.5', :group => :test
 ```
 
 In your `spec_helper.rb`, get Combustion to set itself up - which has to happen before you introduce `rspec/rails` and - if being used - `capybara/rails`. Here's an example within context:
 
 ```ruby
-require 'rubygems'
-require 'bundler/setup'
+require 'bundler'
 
-require 'combustion'
-require 'capybara/rspec'
+Bundler.require :default, :development
 
+# If you're using all parts of Rails:
 Combustion.initialize! :all
+# Or, load just what you need:
+# Combustion.initialize! :active_record, :action_controller
 
 require 'rspec/rails'
-require 'capybara/rails'
+# If you're using Capybara:
+# require 'capybara/rails'
 
 RSpec.configure do |config|
   config.use_transactional_fixtures = true
 end
 ```
