+# Homelab
+A quick guide on setting up new VMs / Servers in the Homelab with proxmox.
+## Pre-Requisites
+1. A tailscale setup, with a preauthkey with a long expiry. This will be baked into the nixos ISO for easy access to new VMs
+# Install Guide
+
+1. Generate ISO
+
+This is to be run on the proxmox node. 
+
+```bash
+TAILSCALE_AUTH_KEY=<preauthkey> nix build --refresh --verbose --impure "git+https://gitea.ts.yadunut.com/yadunut/homelab.git#generate-iso"
+```
+Copy ISO Over to the VM
+```bash
+cp ./result/iso/nixos-yadunut.iso /var/lib/vz/template/iso
+```
+
+2. Create virtual machines on proxmox
+
+This command is to be run on the proxmox Node / via SSH. Follow the guide to setup the VM.
+
+TODO: This currently only works on falcon, to support other nodes, I need to create new VMs via the API with `pvesh` instead of the `qm` tool. 
+```bash
+nix run --refresh --verbose "git+https://gitea.ts.yadunut.com/yadunut/homelab.git.#create-vm"
+```
+Copy the IP address 
+
+3. Use nixos-anywhere to bootstrap virtual machines
+
+```bash
+nix run ".#bootstrap"`
+```
+
+# Process to creating a New Machine
+1. Create an ISO and transfer it over to Proxmox if it doesn't already exist
+2. Create the VMs on Proxmox with the `nix run "git+https://gitea.ts.yadunut.com/yadunut/homelab.git#create-vm"` command
+3. Create the machine configuration in `./nixos/machines`
+4. With NixOS anywhere, 
+
+# Problem
+I want to copy the tailscale key over to the newly initialized VMs. I guess the VMs don't need to have tailscale setup on launch of the ISO unless I bake it into the ISO :thinking:
+
+Wait I could bake it into the ISO. 
+
+It has been baked into the ISO. So now, I can connect to the VM from without being in the same network :)
+
+Now that I have VMs booted into the ISO, I need to setup the VMs. This would firstly require:
+1. Generating the host keys
+2. Tailscale encrypt with age, and transfer to the VM
+3. Encrypting
