+# Multiarch Docker image build pipeline
+
+Include this repository as `.woodpecker` submodule in your Git repository
+
+This pipeline follows some patterns:
+
+* All images are built multiarch amd64 and arm64 both
+* Image names are consistently mapped between Git repo and Harbor, so
+  git.k-space.ee/foo/bar becomes harbor.k-space.ee/foo/bar
