 ## Development
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. Run `bundle exec index_shotgun` to use the gem in this directory, ignoring other installed copies of this gem.
