+# Meshdb Environment Setup
+
+1. Configure a user for the [proxmox provider](https://registry.terraform.io/providers/Telmate/proxmox/latest/docs) and setup env vars.
+2. Setup tfvars + ssh keys
+3. `terraform plan --var-file=your.tfvars`
+4. `terraform apply --var-file=your.tfvars`
+5. Login via serial and figure out the IPs that were recieved from DHCP
+6. SSH into the master node and setup
+```
+curl -sfL https://get.k3s.io | sh -s - server --cluster-init --disable servicelb
+
+echo "cluster-init: true" >> /etc/rancher/k3s/config.yaml
+echo "disable: servicelb" >> /etc/rancher/k3s/config.yaml
+```
+
+7. Install metallb on master node
+
+```

+
+8. Setup each node (from the manager)
+
+`bash setup_node.sh <NODE IP>`
+
+```
+#!/bin/bash
+# setup_node.sh
+MASTER_IP="$(ip addr show eth0 | grep "inet\b" | awk '{print $2}' | cut -d/ -f1)"
+NODE_TOKEN="$(cat /var/lib/rancher/k3s/server/node-token)"
+
+target_host="$1"
+
+ssh -t ubuntu@$target_host "curl -sfL https://get.k3s.io>k3s; sudo bash k3s --server https://${MASTER_IP}:6443 --token $NODE_TOKEN"
+```
+
+9. Install helm chart...
