+## Subareas of interest
+
+As the project adoption increases, and the codebase keeps growing, we’re trying to break it down into self driven subareas of interest.
+Requirements from the [Kubernetes community membership guidelines](https://github.com/kubernetes/community/blob/master/community-membership.md) apply for reviewers, maintainers and any member of these subareas.
+For becoming a member of any particular subarea the following procedure should be satisfied:
+1. Submit a PR.
+2. Propose at community meeting.
+3. Get positive feedback and +1s in the PR and wait one week lazy consensus after agreement.
+
+As of today there are following OWNERS files/Owner groups defining sub areas:
+- [Clusterctl](cmd/clusterctl)
+- [kubeadm Bootstrap Provider (CABPK)](bootstrap/kubeadm)
+- [kubeadm Control Plane Provider (KCP)](controlplane/kubeadm)
+- [Infrastructure Provider Docker (CAPD)](test/infrastructure/docker)
+- [Cluster Managed topologies, ClusterClass](controllers/topology)
+- [Test](test)
+- [Docs](docs)
