## If you update the version here, also update it in .travis.yml and
## README.md. Then push your branch and make sure Travis supports that
## version. Then remind one of the site maintainers that they need to
## run `rvm install <VERSION>` on the build server(s) before they commit
## to master
ruby '2.4.1'

## Used on the build server. If you add a package here (like nokogiri)
## that has non-Gem dependencies (like zlib), please remind the site
## maintainers that they need to manually update the build server(s)
## before they commit to master. If `bundle install` can satisfy all
## your dependencies, then nothing extra needs to be done

## you can put whatever you want here and bundler will tell us humans to
