+# To test the workflow in a presubmit
+#   1. Push to a branch and create a PR
+#   2. Create a new release in GitHub
+#      * Mark it as a pre-release
+#      * Create the release from the branch you pushed
+#      
+#      Using the CLI something like
+# gh release create v0.0.1-pre1 -p --target=jlewi/foyle --title="goreleaser test" --notes="goreleaser test"
+#
+# This will trigger a release from that branch.
+#
+# N.B. You also need a .goreleaser.yaml file to actually configure goreleaser.
