+## serve_hostname
+
+This is a small util app to serve your hostname on TCP and/or UDP.  Useful for testing.
+
+The `serve_hostname` Makefile supports multiple architectures, which means it may cross-compile and build an docker image easily.
+Arch-specific busybox images serve as base images.
+
+If you are releasing a new version, please bump the `TAG` value in the `Makefile` before building the images.
+
+## How to release:
+
+```
+# Build cross-platform binaries
+$ make all-push
+
+# Build for linux/amd64 (default)
+$ make push ARCH=amd64
+# ---> gcr.io/google_containers/serve_hostname-amd64:TAG
+
+$ make push ARCH=arm
+# ---> gcr.io/google_containers/serve_hostname-arm:TAG
+
+$ make push ARCH=arm64
+# ---> gcr.io/google_containers/serve_hostname-arm64:TAG
+
+$ make push ARCH=ppc64le
+# ---> gcr.io/google_containers/serve_hostname-ppc64le:TAG
+
+$ make push ARCH=s390x
+# ---> gcr.io/google_containers/serve_hostname-s390x:TAG
+```
+
+Of course, if you don't want to push the images, run `make all-container` or `make container ARCH={target_arch}` instead.
