+# Docker Image Builds
+
+This monorepo builds multi-architecture Docker images with Buildx.
+Prerequisite: Docker CLI with the `buildx` plugin installed.
+
+Default platforms for release scripts:
+- `linux/amd64`
+- `linux/arm64`
+
+Run from each image directory:
+
+```bash
+./build.sh
+```
+
+Override platforms when needed:
+
+```bash
+PLATFORMS=linux/amd64 ./build.sh
+```
+
+All scripts publish both `${IMAGE}:${GIT_SHA}` and `${IMAGE}:latest` as a multi-platform manifest list.
