+# What does this stuff do?
+Packer is a tool that can create Virtual Machine templates from code. This repository hosts the code for a customized templates used in Siempie's home environment using the Proxmox Hypervisor.  
+
+# Template
+Inside the template packer does:
+ - Install updates
+ - Install tools; curl, qemu-guest agent, sudo and wget.  
+ - Install Ansible user with private key
+ - Clean guest (machine-id, logs, apt cache, etc)
+  
+Other information to know:
+ - Template hostname: `localhost`
+
+ - packer username: `packer`
+ - packer password: `packer`
+ - Ubuntu 24 Template: VM ID 999  
+  
+More info: https://developer.hashicorp.com/packer/docs/intro
+
+| OS | VM Name | VM ID | 
+|----|---------|-------|
+| Ubuntu 24 | ubuntu.template.siempie.internal | 999 |
+
+# Install packer
+Install packer on your system:  
+https://developer.hashicorp.com/packer/tutorials/docker-get-started/get-started-install-cli
+
+# Variables
+Copy the `variables.pkrvars.hcl.example` file to `variables.pkrvars.hcl` and change the variables.
+
+# Initialize the project and install the proxmox provider
+```
+packer init -var-file variables.pkrvars.hcl ubuntu24/packer.pkr.hcl
+```
+
+# Usage
+Ubuntu 24
+```
+packer build -force -var-file variables.pkrvars.hcl ubuntu24/packer.pkr.hcl
+```
+Note: the `-force` flag removes an already existing VM or Template with the same ID (999).
