+# Harmony, Orchestrateur d'infrastructure open-source
+
+**Target Duration:** 25 minutes\
+**Tone:** Friendly, expert-to-expert, inspiring.
+
+---
+
+#### **Slide 1: Title Slide**
+
+- **Visual:** Clean and simple. Your company logo (NationTech) and the Harmony logo.
+
+---
+
+#### **Slide 2: The YAML Labyrinth**
+
+**Goal:** Get every head in the room nodding in agreement. Start with their world, not yours.
+
+- **Visual:**
+  - Option A: "The Pull Request from Hell". A screenshot of a GitHub pull request for a seemingly minor change that touches dozens of YAML files across multiple directories. A sea of red and green diffs that is visually overwhelming.
+  - Option B: A complex flowchart connecting dozens of logos: Terraform, Ansible, K8s, Helm, etc.
+- **Narration:**\
+  [...ADD SOMETHING FOR INTRODUCTION...]\
+  "We love the power that tools like Kubernetes and the CNCF landscape have given us. But let's be honest... when did our infrastructure code start looking like _this_?"\
+  "We have GitOps, which is great. But it often means we're managing this fragile cathedral of YAML, Helm charts, and brittle scripts. We spend more time debugging indentation and tracing variables than we do building truly resilient systems."
+
+---
+
+#### **Slide 3: The Real Cost of Infrastructure**
+
+- **Visual:** "The Jenga Tower of Tools". A tall, precarious Jenga tower where each block is the logo of a different tool (Terraform, K8s, Helm, Ansible, Prometheus, ArgoCD, etc.). One block near the bottom is being nervously pulled out.
+- **Narration:**
+  "The real cost isn't just complexity; it's the constant need to choose, learn, integrate, and operate a dozen different tools, each with its own syntax and failure modes. It's the nagging fear that a tiny typo in a config file could bring everything down. Click-ops isn't the answer, but the current state of IaC feels like we've traded one problem for another."
+
+---
+
+#### **Slide 4: The Broken Promise of "Code"**
+
+**Goal:** Introduce the core idea before introducing the product. This makes the solution feel inevitable.
+
+- **(Initial Visual):** A two-panel slide.
+  - **Left Panel Title: "The Plan"** - A terminal showing a green, successful `terraform plan` output.
+  - **Right Panel Title: "The Reality"** - The _next_ screen in the terminal, showing the `terraform apply` failing with a cascade of red error text.
+- **Narration:**
+  "We call our discipline **Infrastructure as Code**. And we've all been here. Our 'compiler' is a `terraform plan` that says everything looks perfect. We get the green light."
+  (Pause for a beat)
+  "And then we `apply`, and reality hits. It fails halfway through, at runtime, when it's most expensive and painful to fix."
+
+**(Click to transition the slide)**
+
+- **(New Visual):** The entire slide is replaced by a clean screenshot of a code editor (like nvim 😉) showing Harmony's Rust DSL. A red squiggly line is under a config line. The error message is clear in the "Problems" panel: `error: Incompatible deployment. Production target 'gcp-prod-cluster' requires a StorageClass with 'snapshots' capability, but 'standard-sc' does not provide it.`
+- **Narration (continued):**
+  "In software development, we solved these problems years ago. We don't accept 'it compiled, but crashed on startup'. We have real tools, type systems, compilers, test frameworks, and IDEs that catch our mistakes before they ever reach production. **So, what if we could treat our entire infrastructure... like a modern, compiled application?**"
+  "What if your infrastructure code could get compile-time checks, straight into the editor... instead of runtime panics and failures at 3 AM in production?"
+
+---
+
+#### **Slide 5: Introducing Harmony**
+
+**Goal:** Introduce Harmony as the answer to the "What If?" question.
+
+- **Visual:** The Harmony logo, large and centered.
+- **Tagline:** `Infrastructure in type-safe Rust. No YAML required.`
+- **Narration:**
+  "This is Harmony. It's an open-source orchestrator that lets you define your entire stack — from a dev laptop to a multi-site bare-metal cluster—in a single, type-safe Rust codebase."
+
+---
+
+#### **Slide 6: Before & After**
+
+- **Visual:** A side-by-side comparison. Left side: A screen full of complex, nested YAML. Right side: 10-15 lines of clean, readable Harmony Rust DSL that accomplishes the same thing.
+- **Narration:**
+  "This is the difference. On the left, the fragile world of strings and templates. On the right, a portable, verifiable program that describes your apps, your infra, and your operations. We unify scaffolding, provisioning, and Day-2 ops, all verified by the Rust compiler. But enough slides... let's see it in action."
+
+---
+
+#### **Slide 7: Live Demo: Zero to Monitored App**
+
+**Goal:** Show, don't just tell. Make it look effortless. This is where you build the "dream."
+
+- **Visual:** Your terminal/IDE, ready to go.
+- **Narration Guide:**
+  "Okay, for this demo, we're going to take a standard web app from GitHub. Nothing special about it."
+  _(Show the repo)_
+  "Now, let's bring it into Harmony. This is the entire definition we need to describe the application and its needs."
+  _(Show the Rust DSL)_
+  "First, let's run it locally on k3d. The exact same definition for dev as for prod."
+  _(Deploy locally, show it works)_
+  "Cool. But a real app needs monitoring. In Harmony, that's just adding a feature to our code."
+  _(Uncomment one line: `.with_feature(Monitoring)` and redeploy)_
+  "And just like that, we have a fully configured Prometheus and Grafana stack, scraping our app. No YAML, no extra config."
+  "Finally, let's push this to our production staging cluster. We just change the target and specify our multi-site Ceph storage."
+  _(Deploy to the remote cluster)_
+  "And there it is. We've gone from a simple web app to a monitored, enterprise-grade service in minutes."
+
+---
+
+#### **Slide 8: Live Demo: Embracing Chaos**
+
+**Goal:** Prove the "predictable" and "resilient" claims in the most dramatic way possible.
+
+- **Visual:** A slide showing a map or diagram of your distributed infrastructure (the different data centers). Then switch back to your terminal.
+- **Narration Guide:**
+  "This is great when things are sunny. But production is chaos. So... let's break things. On purpose."
+  "First, a network failure." _(Kill a switch/link, show app is still up)_
+  "Now, let's power off a storage server." _(Force off a server, show Ceph healing and the app is unaffected)_
+  "How about a control plane node?" _(Force off a k8s control plane, show the cluster is still running)_
+  "Okay, for the grand finale. What if we have a cascading failure? I'm going to kill _another_ storage server. This should cause a total failure in this data center."
+  _(Force off the second server, narrate what's happening)_
+  "And there it is... Ceph has lost quorum in this site... and Harmony has automatically failed everything over to our other datacenter. The app is still running."
+
+---
+
+#### **Slide 9: The New Reality**
+
+**Goal:** Summarize the dream and tell the audience what you want them to do.
+
+- **Visual:** The clean, simple Harmony Rust DSL code from Slide 6. A summary of what was just accomplished is listed next to it: `✓ GitHub to Prod in minutes`, `✓ Type-Safe Validation`, `✓ Built-in Monitoring`, `✓ Automated Multi-Site Failover`.
+- **Narration:**
+  "So, in just a few minutes, we went from a simple web app to a multi-site, monitored, and chaos-proof production deployment. We did it with a small amount of code that is easy to read, easy to verify, and completely portable. This is our vision: to offload the complexity, and make infrastructure simple, predictable, and even fun again."
+
+---
+
+#### **Slide 10: Join Us**
+
+- **Visual:** A clean, final slide with QR codes and links.
+  - GitHub Repo (`github.com/nation-tech/harmony`)
+  - Website (`harmony.sh` or similar)
+  - Your contact info (`jg@nation.tech` / LinkedIn / Twitter)
+- **Narration:**
+  "Harmony is open-source, AGPLv3. We believe this is the future, but we're just getting started. We know this crowd has great infrastructure minds out there, and we need your feedback. Please, check out the project on GitHub. Star it if you like what you see. Tell us what's missing. Let's build this future together. Thank you."

+# OPNsense PXE Lab Environment
+
+This project contains a script to automatically set up a virtual lab environment for testing PXE boot services managed by an OPNsense firewall.
+
+## Overview
+
+The `pxe_vm_lab_setup.sh` script will create the following resources using libvirt/KVM:
+
+1.  **A Virtual Network**: An isolated network named `harmonylan` (`virbr1`) for the lab.
+2.  **Two Virtual Machines**:
+    *   `opnsense-pxe`: A firewall VM that will act as the gateway and PXE server.
+    *   `pxe-node-1`: A client VM configured to boot from the network.
+
+## Prerequisites
+
+Ensure you have the following software installed on your Arch Linux host:
+
+*   `libvirt`
+*   `qemu`
+*   `virt-install` (from the `virt-install` package)
+*   `curl`
+*   `bzip2`
+
+## Usage
+
+### 1. Create the Environment
+
+Run the `up` command to download the necessary images and create the network and VMs.
+
+```bash
+sudo ./pxe_vm_lab_setup.sh up
+```
+
+### 2. Install and Configure OPNsense
+
+The OPNsense VM is created but the OS needs to be installed manually via the console.
+
+1.  **Connect to the VM console**:
+    ```bash
+    sudo virsh console opnsense-pxe
+    ```
+
+2.  **Log in as the installer**:
+    *   Username: `installer`
+    *   Password: `opnsense`
+
+3.  **Follow the on-screen installation wizard**. When prompted to assign network interfaces (`WAN` and `LAN`):
+    *   Find the MAC address for the `harmonylan` interface by running this command in another terminal:
+        ```bash
+        virsh domiflist opnsense-pxe
+        # Example output:
+        # Interface   Type      Source       Model    MAC
+        # ---------------------------------------------------------
+        # vnet18      network   default      virtio   52:54:00:b5:c4:6d
+        # vnet19      network   harmonylan   virtio   52:54:00:21:f9:ba
+        ```
+    *   Assign the interface connected to `harmonylan` (e.g., `vtnet1` with MAC `52:54:00:21:f9:ba`) as your **LAN**.
+    *   Assign the other interface as your **WAN**.
+
+4.  After the installation is complete, **shut down** the VM from the console menu.
+
+5.  **Detach the installation media** by editing the VM's configuration:
+    ```bash
+    sudo virsh edit opnsense-pxe
+    ```
+    Find and **delete** the entire `<disk>` block corresponding to the `.img` file (the one with `<target ... bus='usb'/>`).
+
+6.  **Start the VM** to boot into the newly installed system:
+    ```bash
+    sudo virsh start opnsense-pxe
+    ```
+
+### 3. Connect to OPNsense from Your Host
+
+To configure OPNsense, you need to connect your host to the `harmonylan` network.
+
+1.  By default, OPNsense configures its LAN interface with the IP `192.168.1.1`.
+2.  Assign a compatible IP address to your host's `virbr1` bridge interface:
+    ```bash
+    sudo ip addr add 192.168.1.5/24 dev virbr1
+    ```
+3.  You can now access the OPNsense VM from your host:
+    *   **SSH**: `ssh root@192.168.1.1` (password: `opnsense`)
+    *   **Web UI**: `https://192.168.1.1`
+
+### 4. Configure PXE Services with Harmony
+
+With connectivity established, you can now use Harmony to configure the OPNsense firewall for PXE booting. Point your Harmony OPNsense scores to the firewall using these details:
+
+*   **Hostname/IP**: `192.168.1.1`
+*   **Credentials**: `root` / `opnsense`
+
+### 5. Boot the PXE Client
+
+Once your Harmony configuration has been applied and OPNsense is serving DHCP/TFTP, start the client VM. It will automatically attempt to boot from the network.
+
+```bash
+sudo virsh start pxe-node-1
+sudo virsh console pxe-node-1
