 ### Building
 
+To build, this container uses Docker's `buildx`, for which on Debian Bookworm it's required to use
+the upstream (docker.com) packages described [[here](https://docs.docker.com/engine/install/debian/)].
+To allow the buildx to build for multi-arch, it's also required to install the Qemu `binfmt`
+emulators, with:
+
+```bash
+docker run --privileged --rm tonistiigi/binfmt --install all
+```
+
+Then, ongoing builds can be cross-platform and take about 1500 seconds on an AMD64 i7-12700T
+The buildx invocation will build 'latest' and then tag it with the current VPP package release,
+which you can get from `vppcfg show version`, like so:
+
 ```bash
 IMG=git.ipng.ch/ipng/vpp-containerlab
 TAG=latest
-docker build --no-cache --build-arg REPO=release -f docker/Dockerfile.bookworm -t $IMG docker/
+docker buildx build --push --platform linux/arm64,linux/amd64 \
-docker image tag $IMG $IMG:$TAG
+  --tag $IMG:$TAG -f docker/Dockerfile docker/
-docker push $IMG
+
-docker push $IMG:$TAG
+TAG=v25.02-release
+docker buildx build --push --platform linux/arm64,linux/amd64 \
+  --tag $IMG:$TAG -f docker/Dockerfile docker/

 we then generate a config file called `/etc/vpp/clab.vpp` which contains the necessary VPP commands
 to take control over these `veth` pairs.
