The library should support 3 different ways to declare config: https://github.com/samueljseay/recaptcha/releases/tag/2.1.1 I haven't looked in depth in to your issues yet, but I'll see if these still work for me. If you want to update your PR so that the README reflects the release notes that'd be appreciated though.

@sobolevn you've been following the issues people have had.. do you know if the config currently works as stated in the release docs?

@samueljseay I am using {:recaptcha, "~> 2.0}" with not issues.
https://github.com/elixir-lang-moscow/site/blob/master/mix.exs#L59

Here's how the configuration is made: https://github.com/elixir-lang-moscow/site/blob/master/config/config.exs#L77

And my environment variables:

=== elixir-lang-moscow Config Vars
....
RECAPTCHA_PRIVATE_KEY: ....KbVq....
RECAPTCHA_PUBLIC_KEY: ....gurMCr8i...

Closing this. I'll make a PR to update the docs to reflect the release notes.
