Summary of changes: - "workshopctl" is now "labctl" - it can handle deployment of VMs but also of managed Kubernetes clusters (and therefore, it replaces the "prepare-tf" directory) - support for many more providers has been added Check the README.md, in particular the "directory structure"; it has the most important information.
