+  # Note that if you're using cargo-dist, this will "race" the Release workflow
+  # that actually builds the Github Release that oranda tries to read (and
+  # this will almost certainly complete first). As a result you will publish
+  # docs for the latest commit but the oranda landing page won't know about
+  # the latest release. The workflow_run trigger below will properly wait for
+  # cargo-dist, and so this half-published state will only last for ~10 minutes.
+  #
+  # If you only want docs to update with releases, disable this, or change it to
+  # a "release" branch. You can, of course, also manually trigger a workflow run
+  # when you want the docs to update.

+  # however that Github's UI is wonky when you use workflow_run, and won't
+  # show this workflow as part of any commit. You have to go to the "actions"
+  # tab for your repo to see this one running (the gh-pages deploy will also
