 First, check your dependencies: Ensure that you have Ruby 1.9.x installed:
 
-  ruby --version
+    ruby --version
 
 Install the project's gem dependencies:
 
-  bundle install
+    bundle install
 
 Create the development and test databases, using the settings specified in `config/database.yml`. You can then load the schema and some seed data with the following command:
 
-  rake db:schema:load db:seed
+    rake db:schema:load db:seed
 
 At long last, your dreams of spinning up a development server can be realised:
 
-  rails server
+    rails server
 
 
 ## Testing
 
 Tests, both unit and integration, are based on RSpec. To run the test suite, first prepare the test database:
 
-  bundle exec rake db:test:load
+    bundle exec rake db:test:load
 
 Then the tests can be run with:
 
-  bundle exec rspec spec
+    bundle exec rspec spec
 
 The site is configured to use
 [Spork](https://github.com/sporkrb/spork) to reduce the pre-test
 startup time while Rails loads. To use it, first start up a spork
 instance:
 
-  bundle exec spork
+    bundle exec spork
 
 When that's ready, you can run RSpec with the --drb flag:
 
-  bundle exec rspec --drb spec
+    bundle exec rspec --drb spec
