After checking out the repo, run bin/setup to install dependencies.

This is a hobby project and some of the gems used rely on old and unsupported versions of ruby (2.4.1) and proj (v5). For the sake of time I've just fixed the version in the setup script. You'll need to run the setup which uses homebrew and rbenv to install dependencies so it's OSX only unfortunately.

You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
