Uncomment what you need. i.e. Slack, Crashlytics...

Ahh -- how would one actually use this .. I also have a fastlane (that works) under the iOS and android folders. But I'd like to have a higher level one at the top level .. but a "fastlane init" complains there is no iOS project found, etc. etc. I'd also like a Gemfile etc. to make sure it's all included ??

I have the same question.
