In particular, you'll need to remove our private podspec repo from the `Podfile`, and update the certificate repo in `fastlane/Matchfile`. If you have issues beyond that, feel free to [drop us a note](mailto:ios@vokal.io).

 If you're updating the templates, you'll note that there are Vokal-fied versions of several templates in this project - this is to facilitate making sure that certain stock files which would otherwise be created are not created.
