From the Gemfile, this includes

• https://github.com/fastlane/TaskQueue
• https://github.com/fastlane/fastlane
• https://github.com/fastlane/fastfile-parser

Also at the time of writing, we have a few forks, that we either need to get merged, or publish our own fork

• https://github.com/fastlane/ruby-git
• https://github.com/GoogleCloudPlatform/google-cloud-ruby

We decided to pause our work on fastlane.ci to focus on the core fastlane product as we have a lot on the roadmap. You can find more information on the main GitHub page. This issue will be auto-closed 👍
