+# buildBuilderImage.yml
+#
+# Workflow to build a multiarch Docker image that includes all of the tools for
+# building maiko for linux.  Intended to be used (exclusively?) by the github
+# actions that build maiko releases - e.g., buildRelease.yml.
+#
+# The purpose is to make the maiko github actions quicker and less resource
+# consuming by not hving to intll the tools every time and instead just reuse
+# this Docker image.
