$ cue help modules
Modules are how CUE publishes packages and manages dependencies.

A module is a collection of packages that are released, versioned, and
distributed together. Modules are downloaded from OCI-compliant
artifact registries.

The Central Registry for CUE modules (registry.cue.works) is
used as the source for external modules by default.
