  # automatic updating of go.mod described above. Instead, it fails when any changes
  # to go.mod are needed. This setting is most useful to check that go.mod does
  # not need updates, such as in a continuous integration and testing system.

  # directory holds the correct copies of dependencies and ignores
  # the dependency descriptions in go.mod.
