To grow the developer community, SIG Windows  released multiple [tools](https://github.com/kubernetes-sigs/sig-windows-dev-tools/). The new tools support multiple CNI providers (Antrea, Calico), can run on multiple platforms (any vagrant compatible provider, such as Hyper-V, VirtualBox, or vSphere).
