There is a lot of overlap with the [Kubernetes Software Conformance Working Group](https://github.com/cncf/k8s-conformance/blob/master/README-WG.md) with this sub project as well. The github group [cncf-conformance-wg](https://github.com/orgs/kubernetes/teams/cncf-conformance-wg) enumerates the folks on this working group. Look for the `area/conformance` label in the kubernetes repositories to mark [issues](https://github.com/kubernetes/kubernetes/issues?q=is%3Aissue+is%3Aopen+label%3Aarea%2Fconformance) and [PRs](https://github.com/kubernetes/kubernetes/pulls?q=is%3Apr+is%3Aopen+label%3Aarea%2Fconformance)
