but must be done manually after the package signing and upload
to download.ceph.com.

 5. Build Containers
 ===================
 
-Architecture-specific containers are built during the ceph build and
-pushed to quay.ceph.io/ceph/prerelease-{amd64,arm64}, containing the
-packages built in that ceph build.  The prerelease 'fat' container,
-or manifest-list container, that refers to both arch-specific containers,
-is built by hand using the command "make-manifest-list.py" in
-ceph.git:src/container/make-manifest-list.py.  Note that you must
-be logged into the appropriate container repos for any of these
-manipulations: quay.ceph.io for fetching prerelease arch-specific
-containers and pushing the prerelease manifest-list container, and
-quay.io for promoting the prerelease containers to released containers.
+Unlike CI builds, which have access to packages in the correct form for
+the container, release builds do not, because the build does not 
+sign the packages.  Thus, release builds do not build the containers.
+This must be done after :ref:`Signing and Publishing the Build`.
+
+Architecture-specific containers are built first, and pushed to
+quay.ceph.io/ceph/prerelease-{amd64,arm64}.  Note: this must be done on
+both architectures.
+
+#. Use a host with a relatively-recent version of podman and skopeo available.
+   CentOS/RHEL/Fedora usually have later versions than Ubuntu, but Ubuntu 22.04
+   or later are probably ok.
+
+#. Copy and run this shell wrapper for building a container (in container/ is
+   assumed below, to invoke ``./build.sh``), replacing the values in ``<>`` as
+   appropriate:
+
+     .. code-block:: bash

+   ``quay.ceph.io/ceph/prerelease-amd64`` and
+   ``quay.ceph.io/ceph/prerelease-arm64``.
+
