Just fyi:
Neither are critical but I recommend your repo have underscore instead of hyphen for an elixir project, and using "ex" in the name of your project is generally (informally) considered to be a signal for low code quality in the community.
Thanks for the note, it's changed to underscore now.
Regarding the "ex" prefix, it's a common pattern for Elixir libraries.
