 # tag). It is a separate job so that a failing mirror leaves the release and its
 # tag standing: the release is the product, the wiki a view of it. It does not
 # run for a `-beta.N` candidate, for which `release` sets `skip`.
+#
+# `converters` is the first job: the converter tests against the real documents of the private
+# repository `torben/chemenu-testfiles` (converters.yml has the reasoning and is the reference for
+# the steps; the two are kept in step by hand, because this instance's support for calling one
+# workflow from another is not something this repository relies on). `release` waits for it with
+# `needs:`, so a red harness stops the run before a release or a tag exists. For a candidate it
+# decides `skip` the way `release` does and ends after its first steps.
