 # Validates cocina model changes by loading each object into cocina to determine if an error is raised.
+# Also, transforms the cocina model to MODS.
 # This should be run on sdr-deploy since it requires using a version of cocina models that is not the latest release.
 # To select the cocina model version to test, adjust the Gemfile.
 # For example, gem 'cocina-models', github: 'sul-dlss/cocina-models', branch: 'test_me'
