 ## Names
 
-Names are generally client-provided.  Only one object of a given kind can have a given name at a time (i.e., they are spatially unique).  But if you delete an object, you can make a new object with the same name.  Names are used to refer to an object in a resource URL, such as `/api/v1/pods/some-name`.   By convention, the names of Kubernetes resources should be up to maximum length of 253 characters and consist of lower case alphanumeric characters, `-`, and `.`, but certain resources have more specific restrictions.  See the [identifiers design doc](https://git.k8s.io/community/contributors/design-proposals/architecture/identifiers.md) for the precise syntax rules for names.

 ## UIDs
 
-UIDs are generated by Kubernetes.  Every object created over the whole lifetime of a Kubernetes cluster has a distinct UID (i.e., they are spatially and temporally unique).
