`Object Metadata` section is misleading, as the Concept's overview is covering what master and non-master nodes are and list of objects. But there is no discussion on `Object Metadata` till the end and all of sudden there is Object Metadata section with no background introduction or definition, and just a reference to `Annotations` which is confusing if you read the content from the beginning. So it would be better to remove this as it is covered later here `https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations/`.
