$ cue help mod publish
WARNING: THIS COMMAND IS EXPERIMENTAL.

Publish the current module to an OCI registry. It consults
$CUE_REGISTRY to determine where the module should be published (see
"cue help environment" for details). Also note that this command does
no dependency or other checks at the moment.

Note: you must enable the modules experiment with:
	export CUE_EXPERIMENT=modules
for this command to work.

When the --dryrun flag is specified, nothing will actually be written
to a registry, but all other checks will take place.

The --json flag can be used to find out more information about the upload.

The --out flag can be used to write the module's contents to a directory
in OCI Image Layout format. See this link for more details on the format:
https://github.com/opencontainers/image-spec/blob/8f3820ccf8f65db8744e626df17fe8a64462aece/image-layout.md
