+# Prerequisites
+There are two dependencies that are not managed through the metal3 chart because are related to applications that have a cluster-wide scope: `cert-manager` and a LoadBalancer Service provider such as `metallb` or `kube-vip`.
+
+## Cert Manager
+In order to successfully deploy metal3 the cluster must have already installed the `cert-manager`.
+
+You can install it through `helm` with:
+```bash
+helm repo add jetstack https://charts.jetstack.io
+helm repo update
+helm install \
+  cert-manager jetstack/cert-manager \
+  --namespace cert-manager \
+  --create-namespace \
+  --version v1.11.1 \
+  --set installCRDs=true
+```
+, or via `kubectl` with:
+```bash
+kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.11.1/cert-manager.yaml
+```
+
+## MetalLB (Optional)
+Ironic currently requires a staticIP address and MetalLB is one option to achieve that.
+
+1. If K3s is used as Kubernetes distribution, then it should be started with `--disable=servicelb` flag. Ref https://metallb.universe.tf/configuration/k3s/
+2. Find 1 free IP address in the network.
+3. Install `MetalLB` through `helm` with:
+
+```bash
+helm repo add suse-edge https://suse-edge.github.io/charts
+helm install \
+  metallb suse-edge/metallb \
+  --namespace metallb-system \
+  --create-namespace
+```
+
+4. Provide the IP pool configuration with:
+
+```bash
+export STATIC_IRONIC_IP=<STATIC_IRONIC_IP>
+
+cat <<-EOF | kubectl apply -f -
+apiVersion: metallb.io/v1beta1
+kind: IPAddressPool
+metadata:
+  name: ironic-ip-pool
+  namespace: metallb-system
+spec:
+  addresses:
+  - ${STATIC_IRONIC_IP}/32
+  serviceAllocation:
+    priority: 100
+    serviceSelectors:
+    - matchExpressions:
+      - {key: app.kubernetes.io/name, operator: In, values: [metal3-ironic]}
+EOF
+
+cat <<-EOF | kubectl apply -f -
+apiVersion: metallb.io/v1beta1
+kind: L2Advertisement
+metadata:
+  name: ironic-ip-pool-l2-adv
+  namespace: metallb-system
+spec:
+  ipAddressPools:
+  - ironic-ip-pool
+EOF
+```
+
+5. Create new values.yaml file that will override some of the default properties:
+
+```bash
+TMP_DIR=$(mktemp -d)
+cat > ${TMP_DIR}/values.yaml << EOF
+global:
+  ironicIP: "<STATIC_IRONIC_IP>"
+EOF
+```
+
+# Install
+
+```bash
+helm install \
+  metal3 suse-edge/metal3 \
+  --namespace metal3-system \
+  --create-namespace
+  -f ${TMP_DIR}/values.yaml
+```
+
+# How to upgrade the chart
+1. Run `helm dependency update .` in this chart to download/update the dependent charts.
+
+2. Identify the appropriate subchart values settings and create an appropriate override values YAML file.
+   * Ensure that the relevant ironic and baremetal-operator settings match.
+
+3. Install the chart using a command like the following:
+
+```console
+$ helm upgrade heavy-metal . --namespace metal-cubed --create-namespace --install --values ~/overrides.yaml
+```
