+# Docker build (for arm nodes using qemu)
+
+- Install docker CLI https://daniel.es/blog/how-to-install-docker-in-wsl-without-docker-desktop/
+- For reference: Guide for setting up multiarch build support: https://docs.docker.com/build/building/multi-platform/
+- Configure qemu emulation for arm on x86_64:
+    - docker buildx create --name multi-arch-builder --use
+    - docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
+- docker buildx inspect --bootstrap
+- Before building and pushing: Copy the .env-example file to .env and enter auth info inside it
+- run ./build.sh (executes docker buildx build command to build an image on a x86 host that can run on an arm node, e.g.: 
+    docker buildx build --platform linux/arm64 --load -t $IMAGE . --build-arg http_proxy=$http_proxy --build-arg https_proxy=$https_proxy --build-arg no_proxy=$no_proxy)
+    Multiarch images cannot be loaded into the deamon using --load but need to be pushed into a registry directly using --push or be exported to a file 
+
+# Docker push image to OCI
+
+
+- run .
