# elixir-node-ruby

The `elixir-node-ruby` is a variant of `circleci/elixir` Dockerfiles that adds Ruby on top of `elixir:*-node`, so that `license_finder`, a Ruby Gem, can scan Elixir (`mix`) and Node dependencies in [POA Network](https://github.com/poanetwork) repositories, such as https://github.com/poanetwork/poa-explorer.
