+# This workflow file is named 'more-ci' and is used to run additional CI checks

+# across multiple operating systems and OCaml compiler versions.

+# Compared to the main 'ci.yml' job, this skips some steps that are not
+# necessary to check for every combination of os and ocaml-compiler, such as
+# generating coverage report, linting odoc, opam and fmt, etc.
+#
+# We prefer to keep it separate from the main CI workflow because we find it
+# more readable, over having too many conditional steps in the same job.
