 1. What areas and/or subprojects does your group need the most help with?
    Any areas with 2 or fewer OWNERs? (link to more details)
 
-   - 
+   - There are some packages that API Machinery owns and come out usually in our triage meetings, and that we most likely don't know much about: this happens often when Kubernetes is upgrading libraries for example - dependency updates span multiple SIGs due to which the entire PR also comes under the purview of API Machinery. 
-   -
+   - Technical support for triages could have improvements, for example sometimes we remove API Machinery in PRs, and every update to the issue / PR get's us re-tagged again.
-   -
+   - The ecosystem of the different Kubernetes Clients that we own grows more or less organically. Client-go and
+   Python-client are probably the bigger ones.
+   - The subprojects that have a total reviewer + approver count <= 2 across all its OWNERS files are as follows:
+      - https://github.com/kubernetes-client/c (count: 2)
+      - https://github.com/kubernetes-client/go-base (count: 2)
+      - https://github.com/kubernetes-client/perl (count: 1)
+   - There also exist parts of a subproject that come under review/approver crunch. One example is the [`cacher`](https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/apiserver/pkg/storage/cacher) component. Components like this come under a subproject with enough OWNERS but the particular component itself might be dependent on the expertise of a small subset of these OWNERS.
 
 2. What metrics/community health stats does your group care about and/or measure?

+On the technical health of the SIG, we look at the following metrics tracked in [Devstats](https://k8s.devstats.cncf.io/d/25/open-pr-age-by-repository-group?orgId=1&var-period=q&var-repogroup_name=SIG%20API%20Machinery&var-kind_name=All&from=1640991600000&to=1672527599000&var-repo_name=kubernetes%2Fkubernetes):

 3. Does your [CONTRIBUTING.md] help **new** contributors engage with your group specifically by pointing
    to activities or programs that provide useful context or allow easy participation?
 
-   - No, it can be improved. The README points contributors to SIG meetings and triage meetings that happens twice a week.

 6. Are there ways end users/companies can contribute that they currently are not?
    If one of those ways is more full time support, what would they work on and why?
 
-   -
+   - There currently isn't a charted course for end users/companies to get more involved.
-   -
+   - The most common, albeit ad-hoc, method has been showing up in the SIG meeting and starting/continuing discussions on the slack channel.
+   - There is plenty of areas were the SIG could use help in reviewing and maintaining the code, but it's a complicated code base to ramp up. If people don't stick around long enough, the effort does not make sense.
