-# This workflow periodically creates new environment lock files based on the newest
-# available packages and dependencies.
-#
-# Environment specifications are given as conda environment.yml files found in
-# `requirements/ci/py**.yml`.  These state the packages required, the conda channels
-# that the packages will be pulled from, and any versions of packages that need to be
-# pinned at specific versions.
-#
-# For environments that have changed, a pull request will be made and submitted
-# to the main branch
+# Updates the environment lock files. See the called workflow in the
+# scitools/workflows repo for more details.
