@lmdaly thank you for this PR!

I'm not at all familiar with topology or with device plugins. The documentation overall made sense to me.
Do you think it would be useful for https://kubernetes.io/docs/concepts/scheduling/kube-scheduler/ to link to this new page once it exists? Or any other pages?

I spotted a few lines where the wording isn't in SIG Docs' recommended style, and I've suggested some changes. I hope these are helpful.

Thanks for the review @sftim, very helpful! I have made some changes based on the comments.

Topology Manager is confined to the node and only influences decisions when the pod has been scheduled onto a node. I think it would be good if CPU Manager and Device Plugin docs link to Topology Manager, and potentially the Kubelet doc?

Hi. I probably won't have time to provide more feedback between now and the v1.16 release.

@simplytunde that's looking good to me!

@lmdaly Overall, it looks good but I will like to address this part.

The Topology Manager currently: - Works on Nodes with the static CPU Manager Policy enabled. See control CPU Management Policies - Works on Pods in the Guaranteed QOS Class QoS class If these conditions are met, Topology Manager will align CPU and device requests.

Add a blank line before - Works on Nodes with the static CPU Manager Policy... if a list is intended here. Also, I noticed the repeated QOS Class

@simplytunde Done! Let me know if the list is formatted correctly.
