+== Deploying TripleO With Multiple Cells
+
+A TripleO Standalone setup creates only a single Nova v2 cell, with a combined controller and compute services on it.
+In order to deploy multiple compute cells for adoption testing (without Ceph), create a 5 VMs, with the following requirements met:
+
+* Named `edpm-compute-0` .. `edpm-compute-4`.
+* Running RHEL 9.2, with RHOSP 17.1 repositiries configured.
+* Can login via SSH without a password as the root user, from the hypervisor host.
+* User `zuul` is created, and can sudo without a password, and login via SSH without a password, from the hypervisor host.
+* User `zuul` can login to `edpm-compute-1`, `edpm-compute-2`, `edpm-compute-3`, `edpm-compute-4` nodes via SSH without a password, from the `edpm-compute-0` node,
+by using the generated `/home/zuul/.ssh/id_rsa` private key.
+* RedHat registry credentials are exported on the hypervisor host.
+
+Then invoke the `tripleo` target of `install_yamls`.
+
+For that, you can also adjust as needed and use the following commands
+(instead of an example `rhos-release` commands, use a tool of your choice):
+
+[,bash]
+----
+ export RH_REGISTRY_USER="<insert your registry.redhat.io user>"
+ export RH_REGISTRY_PWD="<insert your registry.redhat.io password>"
+
+cd ~/install_yamls/devsetup
+cat <<EOF > /tmp/osp17_repos
+# Rhos-release steps are only available from the internal RedHat network, use a tool of your choice instead!
+#sudo rhos-release -x
+#sudo rhos-release 17.1
+
+sudo dnf install -y git curl wget util-linux lvm2 podman python3-tripleoclient
