+# Builds fonts either when a prerelease version tag (e.g. v1.2-foo)
+# is created, or when source is changed.
+#
+# When a version tag is created, a pre-release is automatically created.
+#
+# Otherwise, when source changes without a tag being created,
+# the build artifacts are uploaded to github and saved for 1 day.
+# They can be found at https://github.com/rsms/inter/actions/runs/RUNID
