 ## Testing
 
 Currently pull-requests are tested via [test-kitchen using kitchen-vagrant](https://github.com/test-kitchen/kitchen-vagrant).
-See [Jenkinsfile](Jenkinsfile) for more information. 
+See [Jenkinsfile](Jenkinsfile) for more information.
 If you'd like to run them yourself, however, they make not work in all setups. For example they assume `192.168.2.0/24`, host pinning will probably not have a host that's in all set ups, and the template names might not match.
 
 To run Unit tests: `bundle install; bundle exec rspec`
