Hi @jonatas sorry about that, should be fixed now.

[gregorynoma]

Hey @jonatas, I added those files you suggested as well as incorporated some additional changes we made since the original PR!

[jonatas]

Thank you, @gregorynoma! I'll review it again!

This PR is needed. Currently your code doesn't actually support MongoDB at all, but your documentation does, which is misleading.
