Registry, the open source implementation for storing and distributing container images and other content, has been donated to the CNCF. Registry now goes under the name of Distribution, and the documentation has moved to distribution/distribution.

The Docker Hub registry implementation is based on Distribution. Docker Hub implements version 1.0.1 OCI distribution specification. For reference documentation on the API protocol that Docker Hub implements, refer to the OCI distribution specification.
