+Images are built on GitHub Actions pipelines, but in case it for some reason
+needs to be done manually, some notes are preserved here.

+Dependencies
+------------
+
+* Docker with BuildKit support (18.09 or higher),
+
+Multiarch
+---------
+
+Build & push multiarch images using
+
+    make buildx/create
+    make buildx/push
+    make buildx/rm
+
+A guide on how to set up multiarch builds can be found [here].
+The goal was to have a single multiarch repo for each container in the
+registry.
+The approach is to use Docker's new BuildKit builder + the buildx command line
+plugin.
+
+Other possibilities are:
+* use QEMU + multiarch base images directly ([1][1], [2][2]), and create a
+manifest file manually,
+* build natively on multiple architectures (not sure how to combine them in a
+single manifest then though).
