+##############################################################################
+# This is a base image to be used for multi-arch emulation on CI.  To setup
+# your system to correctly support the emulation you'll need to register
+# the qemu static user binaries with your kernel's binfmt_misc infrastructure:
+#
+#   docker run --rm --privileged multiarch/qemu-user-static:register --reset
+#
+# You need to use docker buildx to build this image:
+#  - You might need to download the docker-buildx binary and install it in your system.
+#  - docker buildx create --boostrap --platform ppc64le --driver docker-container --name builder
+#  - docker buildx use builder
+#  - docker buildx build --platform ppc64le --load -t ornladios/adios2:ci-x86_64-power8-ubuntu20.04 <this_directory>
+#
+# To build this image you want to set the following build args:
+#   TARGET_ARCH_SYSTEM=ppc64le - The CPU architecture of the target system.
+#   TARGET_ARCH_DOCKER=ppc64le - The CPU architecture if the target system as
+#                                known by dockerhub. Most of the time this will
+#                                be the same as TARGET_ARCH_SYSTEM but in a few
+#                                cases they're different, e.g. for 64-bit ARM
+#                                you would set TARGET_ARCH_SYSTEM=aarch64 and
+#                                TARGET_ARCH_DOCKER=arm64v8.
+#   TARGET_CPU=power8          - The specific CPU model of the target system
+#                                to emulate.  For example, on ppc64le you
+#                                could set it to power8 or power9 (among others)
+#                                or on aarch64 you could set it to cortex-a72.
