+## Multi-architecture Image Creation
+
+For creating multi-architecture container images, this project uses [manifest-tool](https://github.com/estesp/manifest-tool) to create and manage manifest lists that combine platform-specific images into a single multi-platform reference. This allows container runtimes to automatically select the appropriate image based on the target architecture.
+
+The multi-architecture images are built on different architectures (amd64 and arm64) and then combined using manifest-tool's `push from-args` command, which creates manifest lists pointing to the individual platform-specific images.
