 ## Testing
 
 ### Install prerequisites
 
 Install the latest version of [Bundler](http://gembundler.com)
 
-    $ gem install bundler
+```sh
+$ gem install bundler
+```
 
 Clone the project
 
-    $ git clone https://github.com/berkshelf/vagrant-berkshelf.git
+```sh

+```
 
 and run:

-    $ bundle install
+```sh

 One-time run with Rake
 
-    $ bundle exec rake spec
+```sh
+$ bundle exec rake spec
+```
 
 Or you can setup a quick feedback loop with Guard
