+cd my-wild-cloud
+wild-init
+```
+
+## Cloud configuration
+
+```bash
+cp config.example.yaml config.yaml
+cp secrets.example.yaml secrets.yaml
+```

+
+## Dnsmasq
+
+- Install a Linux machine on your LAN. Record it's IP address in your `config:cloud.dns.ip`.
+- Ensure it is accessible with ssh.
+- From your wild-cloud directory, run `wild-central-generate-setup`.
+- Run `cluster/dnsmasq/bin/create-setup-bundle.sh`
+- Run `cluster/dnsmasq/bin/transfer-setup-bundle.sh`
+
+Now ssh into your dnsmasq machine and do the following:
+
+```bash
+sudo -i
+cd /root/dnsmasq-setup
+./setup.sh
+```
+
+## Cluster Setup
+
+```bash
+# ONE-TIME CLUSTER INITIALIZATION (run once per cluster)
+./init-cluster.sh
+```
+
+### Join control nodes
+
+Boot each nodes with Talos ISO in maintenance mode.
+
+```bash
+./detect-node-hardware.sh <maintenance-ip> <node-number>
+./generate-machine-configs.sh
+talosctl apply-config --insecure -n 192.168.8.168 --file final/controlplane-node-1.yaml
+```
+
+### Cluster bootstrap
+
+After all control plane nodes are configured.
+
+```bash
+# Bootstrap the cluster using any control node
+talosctl bootstrap --nodes 192.168.8.31 --endpoint 192.168.8.31
+
+# Get kubeconfig
+talosctl kubeconfig
+
+# Verify cluster is ready
+kubectl get nodes
+```
+
+### Cluster services
+
+```bash
+./setup/cluster/setup-all.sh
+./setup/cluster/validate-setup.sh
+```
+
+## Installing Wild-Cloud apps
+
+```bash
+wild-apps-list
+wild-app-fetch <app>
+wild-app-config <app>
+wild-app-deploy <app>
+# Optional: Check in app templates.
+```
