+In order to have a reproducible and portable build environment for CI we use a container for building in.  This means that developers can also reproduce the CI environment, to a large degree at least, locally.  This file is located in the tools/docker directory.
+
+The docker image supports both amd64 and arm64. Ensure that the
+'docker-buildx' Debian package is installed (or the equivalent on another
+distribution).
+
+You will need a multi-platform container, otherwise this error is shown::
+
+    ERROR: Multi-platform build is not supported for the docker driver.
+    Switch to a different driver, or turn on the containerd image store, and try again.
+
+You can add one with::
+
+    sudo docker buildx create --name multiarch --driver docker-container --use
+
+Building is supported on both amd64 (i.e. 64-bit x86) and arm64 machines. While
+both amd64 and arm64 happen in parallel, the non-native part will take
+considerably longer as it must use QEMU to emulate the foreign code.
+
+To build the image yourself::
 
 .. code-block:: bash
 
-    sudo docker build -t your-namespace:your-tag .
+    sudo docker buildx build --platform linux/arm64/v8,linux/amd64 -t your-namespace:your-tag .
