 ## Development
 After checking out the repo, run `bundle install` to install dependencies. Then, run `rake spec` to run the tests. 
 Publishing a new version is handled by the [publish workflow](.github/workflows/publish.yml). This workflow publishes a GitHub release to [rubygems](https://rubygems.org/) with the version defined in the release.
