+This creates the `gitea.jde.nz/public/dropshell-build-base:latest` Docker image for your current architecture and loads it into Docker.
+
+For multiarch build (without loading):
+```bash
+cd build-base
+BUILD_MODE=multiarch ./build.sh
+```
+This builds for linux/amd64 and linux/arm64 but keeps the image in the buildx cache only.
