+#
+# Workflow to build a Maiko release that is pushed to github as well as
+# Docker images incorporating the release, which are pushed to Docker Hub.
+# For linux:  release assets are built/pushed for X86_64, aarch64 and arm7vl and 
+#     a multiplatform Docker image is pushed.
+# For macOS:  release assets are built/pushed for X86_64. (No aarch64 as yet.)
+# For Windows:  not supported
+#
+# Note release pushed to github automatically includes source code assets
+# in tar and zip formats.
