Would it be okay if we recommend it the way I described? (ie: make it a `:development`, `:test` dependency for the project) - I could add some documentation on the README --- I think it's reasonable and would not be too restrictive/opinionated to do so; plus: it gives us a use-case context to work/code against with.
