 If you want to test new features as I develop them, you can always point your Gemfile to the repository. Your Gemfile specification looks like this:
 
-```
+```ruby
-gem 'squib', :git => 'git://github.com/andymeneely/squib', :branch => "dev"
+gem 'squib', git: 'git://github.com/andymeneely/squib', branch: 'dev'
 ```
 * The `dev` branch is where I am working on features in-process. I have not done much regression testing at this point, but would love testing feedback nonetheless.
 * The `master` branch is where I consider features and bug that are done and tested, but not released yet.
