-# Includes

-# Additional configuration can be provided through includes.
-# One advantage of include files is that if they are updated upstream, the
-# changes affect all pipelines using that include.
+# Define conditions for when the pipeline will run.
+#   For example:
+#     * On commit
+#     * On merge request
+#     * On manual trigger
+#     * etc.

 #
-# Includes can be overridden by re-declaring anything provided in an include,
-# here in gitlab-ci.yml.
-# https://docs.gitlab.com/ee/ci/yaml/includes.html#override-included-configuration-values
+# Pipelines can also be configured to run on a schedule,though they still must meet the conditions defined in Workflow and Rules. This can be used, for example, to do nightly regression testing:
