+# Cache baseline images tracked by DVC and upload as artifacts.
+#
+# This workflow downloads dvc cache needed by PyGMT tests and uploads them as workflow
+# artifacts, which can then be accessed by other GitHub Actions workflows.
+#
+# This workflow serves as a workaround for the DagsHub authentication issue that
+# prevents PRs from forks to access the DVC remote.
+# Related issue: https://github.com/GenericMappingTools/pygmt/issues/4147
+#
+# It is scheduled to run every Sunday at 12:00 (UTC) and on the main branch if there are
+# any changes to the baseline images.
