+### OpenStack Pre-requisites
+
+```bash
+# clone the two repos because they reference the infra one as a relative path
+# so you can't use real helm commands
+git clone https://github.com/openstack/openstack-helm
+git clone https://github.com/openstack/openstack-helm-infra
+# update the dependencies cause we can't use real helm references
+./scripts/openstack-helm-depend-sync.sh keystone
+./scripts/openstack-helm-depend-sync.sh ironic
+```
+
+Label the kubernetes nodes as being openstack enabled:
+```bash
+kubectl label node $(kubectl get nodes -o 'jsonpath={.items[*].metadata.name}') openstack-control-plane=enabled
+```
+
 ### Keystone
+
+Install keystone:
+
+```bash
+helm --namespace openstack template \
+    keystone \
+    ./openstack-helm/keystone/ \
+    -f components/10-keystone/aio-values.yaml \
+    --set endpoints.identity.auth.admin.password="$(kubectl --namespace openstack get secret keystone-admin -o jsonpath='{.data.password}' | base64 -d)" \
+    --set endpoints.oslo_db.auth.keystone.password="$(kubectl --namespace openstack get secret keystone-db-password -o jsonpath='{.data.password}' | base64 -d)" \
+    --set endpoints.oslo_messaging.auth.keystone.password="$(kubectl --namespace openstack get secret keystone-rabbitmq-password -o jsonpath='{.data.password}' | base64 -d)" \
+    --post-renderer $(git rev-parse --show-toplevel)/scripts/openstack-helm-sealed-secrets.sh \
+    | kubectl -n openstack apply -f -
+```
+
+Install the openstack admin client:
+
+```bash
+kubectl -n openstack apply -f https://raw.githubusercontent.com/rackerlabs/genestack/main/manifests/utils/utils-openstack-client-admin.yaml
+```
+
+Test if it's working:
+
+```bash
+kubectl exec -it openstack-admin-client -n openstack -- openstack catalog list
+kubectl exec -it openstack-admin-client -n openstack -- openstack service list
+```

+
+### Ironic
+
+First we need to update the `./components/13-ironic/aio-values.yaml` file and adjust a
+setting to match our environment.
+
+Change the network.pxe.device to be the network device on the physical host you'll
+use for pxe network, for example a different network layout may use `eno2` for pxe.
+
+```yaml
+network:
+  pxe:
+    device: ens1f0
+```
+
+Install the OpenStack Ironic helm chart using our custom aio-values.yaml overrides:
+
+```bash
+helm --namespace openstack template \
+    ironic \
+    ./openstack-helm/ironic/ \
+    -f components/13-ironic/aio-values.yaml \
+    --set endpoints.identity.auth.admin.password="$(kubectl --namespace openstack get secret keystone-admin -o jsonpath='{.data.password}' | base64 -d)" \
+    --set endpoints.oslo_db.auth.ironic.password="$(kubectl --namespace openstack get secret ironic-db-password -o jsonpath='{.data.password}' | base64 -d)" \
+    --set endpoints.oslo_messaging.auth.ironic.password="$(kubectl --namespace openstack get secret ironic-rabbitmq-password -o jsonpath='{.data.password}' | base64 -d)" \
+    --set endpoints.identity.auth.ironic.password="$(kubectl --namespace openstack get secret ironic-keystone-password -o jsonpath='{.data.password}' | base64 -d)" \
+    --post-renderer $(git rev-parse --show-toplevel)/scripts/openstack-helm-sealed-secrets.sh \
+    | kubectl -n openstack apply -f -
+```
+
+Check if it's working:
+
+```bash
+kubectl exec -it openstack-admin-client -n openstack -- openstack baremetal driver list
+kubectl exec -it openstack-admin-client -n openstack -- openstack baremetal conductor list
+```
