gemfileでRefileをインストールしようとしました。

gem "refile", require: "refile/rails", github: 'manfe/refile'
gem "refile-mini_magick"

そこでbundle installすると、、、

The git source `git://github.com/manfe/refile.git` uses the `git` protocol, which transmits data without encryption. Disable this warning with `bundle config git.allow_insecure true`, or switch to the `https` protocol to keep your data secure.

どなたかご教示いただけますと幸いです。
