+# ---------------------------------------------------------------------------------------------------------
+# This Dockerfile is intended to be built as part of Conduit's CI pipeline.
+# It does not build Conduit in Docker, but just copies the matching build artifact from the build job.
+# As a consequence, this is not a multiarch capable image. It always expects and packages a x86_64 binary.
+#
+# It is mostly based on the normal Conduit Dockerfile, but adjusted in a few places to maximise caching.
+# Credit's for the original Dockerfile: Weasy666.
