+
+## Write small P-R
+
+Aim for the smallest piece of work that is mergeable.
+
+Mergeable means that :
+
+- it does not break the build
+- it moves the codebase one step forward
+
+P-Rs can be many things, they do not have to be complete features.
+
+### What a P-R **should** be
+
+- Introduce a new trait : This will be the place to discuss the new trait addition, its design and implementation
+- A new implementation of a trait : a new concrete implementation of the LoadBalancer trait
+- A new CI check : something that improves quality, robustness, ci performance
+- Documentation improvements
+- Refactoring
+- Bugfix
+
+### What a P-R **should not** be
+
+- Large. Anything over 200 lines (excluding generated lines) should have a very good reason to be this large.
+- A mix of refactoring, bug fixes and new features.
+- Introducing multiple new features or ideas at once.
+- Multiple new implementations of a trait/functionnality at once
+
+The general idea is to keep P-Rs small and single purpose.
+
+## Commit message formatting
+
+We follow conventional commits guidelines.

+## 1 · The Harmony Philosophy
 
-## Core architecture
+Infrastructure is essential, but it shouldn’t be your core business. Harmony is built on three guiding principles that make modern platforms reliable, repeatable, and easy to reason about.
 
-![Harmony Core Architecture](docs/diagrams/Harmony_Core_Architecture.drawio.svg)
-````
-## Supporting a new field in OPNSense `config.xml`
+| Principle                              | What it means for you                                                                                                                                                                |
+| -------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| **Infrastructure as Resilient Code**   | Replace sprawling YAML and bash scripts with type-safe Rust. Test, refactor, and version your platform just like application code.                                                   |
+| **Prove It Works — Before You Deploy** | Harmony uses the compiler to verify that your application’s needs match the target environment’s capabilities at **compile-time**, eliminating an entire class of runtime outages.   |
+| **One Unified Model**                  | Software and infrastructure are a single system. Harmony models them together, enabling deep automation—from bare-metal servers to Kubernetes workloads—with zero context switching. |
 
-Two steps:
-- Supporting the field in `opnsense-config-xml`
-- Enabling Harmony to control the field
+These principles surface as simple, ergonomic Rust APIs that let teams focus on their product while trusting the platform underneath.
 
-We'll use the `filename` field in the `dhcpcd` section of the file as an example.
+---
 
-### Supporting the field
+## 2 · Quick Start
 
-As type checking if enforced, every field from `config.xml` must be known by the code. Each subsection of `config.xml` has its `.rs` file. For the `dhcpcd` section, we'll modify `opnsense-config-xml/src/data/dhcpd.rs`.
+The snippet below spins up a complete **production-grade Rust + Leptos Webapp** with monitoring. Swap it for your own scores to deploy anything from microservices to machine-learning pipelines.
 
-When a new field appears in the xml file, an error like this will be thrown and Harmony will panic :
-```
-     Running `/home/stremblay/nt/dir/harmony/target/debug/example-nanodc`
-Found unauthorized element filename
-thread 'main' panicked at opnsense-config-xml/src/data/opnsense.rs:54:14:
-OPNSense received invalid string, should be full XML: ()

+# Architecture Decision Record: Multi-Tenancy Strategy for Harmony Managed Clusters
+
+Initial Author: Jean-Gabriel Gill-Couture
+
+Initial Date: 2025-05-26
+
+## Status
+
+Proposed
+
+## Context
+
+Harmony manages production OKD/Kubernetes clusters that serve multiple clients with varying trust levels and operational requirements. We need a multi-tenancy strategy that provides:
+
+1. **Strong isolation** between client workloads while maintaining operational simplicity
+2. **Controlled API access** allowing clients self-service capabilities within defined boundaries
+3. **Security-first approach** protecting both the cluster infrastructure and tenant data
+4. **Harmony-native implementation** using our Score/Interpret pattern for automated tenant provisioning
+5. **Scalable management** supporting both small trusted clients and larger enterprise customers
+
+The official Kubernetes multi-tenancy documentation identifies two primary models: namespace-based isolation and virtual control planes per tenant. Given Harmony's focus on operational simplicity, provider-agnostic abstractions (ADR-003), and hexagonal architecture (ADR-002), we must choose an approach that balances security, usability, and maintainability.
+
+Our clients represent a hybrid tenancy model:
+- **Customer multi-tenancy**: Each client operates independently with no cross-tenant trust
+- **Team multi-tenancy**: Individual clients may have multiple team members requiring coordinated access
+- **API access requirement**: Unlike pure SaaS scenarios, clients need controlled Kubernetes API access for self-service operations
+
+The official kubernetes documentation on multi tenancy heavily inspired this ADR : https://kubernetes.io/docs/concepts/security/multi-tenancy/
+
+## Decision
+
+Implement **namespace-based multi-tenancy** with the following architecture:
+
+### 1. Network Security Model
+- **Private cluster access**: Kubernetes API and OpenShift console accessible only via WireGuard VPN
+- **No public exposure**: Control plane endpoints remain internal to prevent unauthorized access attempts
+- **VPN-based authentication**: Initial access control through WireGuard client certificates
+
+### 2. Tenant Isolation Strategy
+- **Dedicated namespace per tenant**: Each client receives an isolated namespace with access limited only to the required resources and operations
+- **Complete network isolation**: NetworkPolicies prevent cross-namespace communication while allowing full egress to public internet
+- **Resource governance**: ResourceQuotas and LimitRanges enforce CPU, memory, and storage consumption limits
+- **Storage access control**: Clients can create PersistentVolumeClaims but cannot directly manipulate PersistentVolumes or access other tenants' storage
+
+### 3. Access Control Framework
+- **Principle of Least Privilege**: RBAC grants only necessary permissions within tenant namespace scope
+- **Namespace-scoped**: Clients can create/modify/delete resources within their namespace
+- **Cluster-level restrictions**: No access to cluster-wide resources, other namespaces, or sensitive cluster operations
+- **Whitelisted operations**: Controlled self-service capabilities for ingress, secrets, configmaps, and workload management
+
+### 4. Identity Management Evolution
+- **Phase 1**: Manual provisioning of VPN access and Kubernetes ServiceAccounts/Users
+- **Phase 2**: Migration to Keycloak-based identity management (aligning with ADR-006) for centralized authentication and lifecycle management
+
+### 5. Harmony Integration
+- **TenantScore implementation**: Declarative tenant provisioning using Harmony's Score/Interpret pattern
+- **Topology abstraction**: Tenant configuration abstracted from underlying Kubernetes implementation details
+- **Automated deployment**: Complete tenant setup automated through Harmony's orchestration capabilities
+
+## Rationale
+
+### Network Security Through VPN Access
+- **Defense in depth**: VPN requirement adds critical security layer preventing unauthorized cluster access
+- **Simplified firewall rules**: No need for complex public endpoint protections or rate limiting
+- **Audit capability**: VPN access provides clear audit trail of cluster connections
+- **Aligns with enterprise practices**: Most enterprise customers already use VPN infrastructure
+
+### Namespace Isolation vs Virtual Control Planes
+Following Kubernetes official guidance, namespace isolation provides:
+- **Lower resource overhead**: Virtual control planes require dedicated etcd, API server, and controller manager per tenant
+- **Operational simplicity**: Single control plane to maintain, upgrade, and monitor
+- **Cross-tenant service integration**: Enables future controlled cross-tenant communication if required
+- **Proven stability**: Namespace-based isolation is well-tested and widely deployed
+- **Cost efficiency**: Significantly lower infrastructure costs compared to dedicated control planes
+
+### Hybrid Tenancy Model Suitability
+Our approach addresses both customer and team multi-tenancy requirements:
+- **Customer isolation**: Strong network and RBAC boundaries prevent cross-tenant interference
+- **Team collaboration**: Multiple team members can share namespace access through group-based RBAC
+- **Self-service balance**: Controlled API access enables client autonomy without compromising security
+
+### Harmony Architecture Alignment
+- **Provider agnostic**: TenantScore abstracts multi-tenancy concepts, enabling future support for other Kubernetes distributions
+- **Hexagonal architecture**: Tenant management becomes an infrastructure capability accessed through well-defined ports
+- **Declarative automation**: Tenant lifecycle fully managed through Harmony's Score execution model
+
+## Consequences
+
+### Positive Consequences
+- **Strong security posture**: VPN + namespace isolation provides robust tenant separation
+- **Operational efficiency**: Single cluster management with automated tenant provisioning
+- **Client autonomy**: Self-service capabilities reduce operational support burden
+- **Scalable architecture**: Can support hundreds of tenants per cluster without architectural changes
+- **Future flexibility**: Foundation supports evolution to more sophisticated multi-tenancy models
+- **Cost optimization**: Shared infrastructure maximizes resource utilization
+
+### Negative Consequences
+- **VPN operational overhead**: Requires VPN infrastructure management
+- **Manual provisioning complexity**: Phase 1 manual user management creates administrative burden
+- **Network policy dependency**: Requires CNI with NetworkPolicy support (OVN-Kubernetes provides this and is the OKD/Openshift default)
+- **Cluster-wide resource limitations**: Some advanced Kubernetes features require cluster-wide access
+- **Single point of failure**: Cluster outage affects all tenants simultaneously
+
+### Migration Challenges
+- **Legacy client integration**: Existing clients may need VPN client setup and credential migration
+- **Monitoring complexity**: Per-tenant observability requires careful metric and log segmentation
+- **Backup considerations**: Tenant data backup must respect isolation boundaries
+
+## Alternatives Considered
+
+### Alternative 1: Virtual Control Plane Per Tenant
+**Pros**: Complete control plane isolation, full Kubernetes API access per tenant
+**Cons**: 3-5x higher resource usage, complex cross-tenant networking, operational complexity scales linearly with tenants
+
+**Rejected**: Resource overhead incompatible with cost-effective multi-tenancy goals
+
+### Alternative 2: Dedicated Clusters Per Tenant
+**Pros**: Maximum isolation, independent upgrade cycles, simplified security model
+**Cons**: Exponential operational complexity, prohibitive costs, resource waste
+
+**Rejected**: Operational overhead makes this approach unsustainable for multiple clients
+
+### Alternative 3: Public API with Advanced Authentication
+**Pros**: No VPN requirement, potentially simpler client access
+**Cons**: Larger attack surface, complex rate limiting and DDoS protection, increased security monitoring requirements
+
+**Rejected**: Risk/benefit analysis favors VPN-based access control
+
+### Alternative 4: Service Mesh Based Isolation
+**Pros**: Fine-grained traffic control, encryption, advanced observability
+**Cons**: Significant operational complexity, performance overhead, steep learning curve
+
+**Rejected**: Complexity overhead outweighs benefits for current requirements; remains option for future enhancement
+
+## Additional Notes
+
+### Implementation Roadmap
+1. **Phase 1**: Implement VPN access and manual tenant provisioning
+2. **Phase 2**: Deploy TenantScore automation for namespace, RBAC, and NetworkPolicy management
+4. **Phase 3**: Work on privilege escalation from pods, audit for weaknesses, enforce security policies on pod runtimes
+3. **Phase 4**: Integrate Keycloak for centralized identity management
+4. **Phase 5**: Add advanced monitoring and per-tenant observability
+
+### TenantScore Structure Preview
+```rust
+pub struct TenantScore {
+    pub tenant_config: TenantConfig,
+    pub resource_quotas: ResourceQuotaConfig,
+    pub network_isolation: NetworkIsolationPolicy,
+    pub storage_access: StorageAccessConfig,
+    pub rbac_config: RBACConfig,
+}
+```
+
+### Future Enhancements
+- **Cross-tenant service mesh**: For approved inter-tenant communication
+- **Advanced monitoring**: Per-tenant Prometheus/Grafana instances
+- **Backup automation**: Tenant-scoped backup policies
+- **Cost allocation**: Detailed per-tenant resource usage tracking
+
+This ADR establishes the foundation for secure, scalable multi-tenancy in Harmony-managed clusters while maintaining operational simplicity and cost effectiveness. A follow-up ADR will detail the Tenant abstraction and user management mechanisms within the Harmony framework.

+# Architecture Decision Record: \<Title\>
+
+Initial Author: Jean-Gabriel Gill-Couture
+
+Initial Date: 2025-06-04
+
+Last Updated Date: 2025-06-04
+
+## Status
+
+Proposed
+
+## Context
+
+As Harmony's goal is to make software delivery easier, we must provide an easy way for developers to express their app's semantics and dependencies with great abstractions, in a similar fashion to what the score.dev project is doing.
+
+Thus, we started working on ways to package common types of applications such as LAMP, which we started working on with `LAMPScore`.
+
+Now is time for the next step : we want to pave the way towards complete lifecycle automation. To do this, we will start with a way to execute Harmony's modules easily from anywhere, starting with locally and in CI environments.
+
+## Decision
+
+To achieve easy, portable execution of Harmony, we will follow this architecture :
+
+- Host a basic harmony release that is compiled with the CLI by our gitea/github server
+    - This binary will do the following : check if there is a `harmony` folder in the current path
+    - If yes
+        - Check if cargo is available locally and compile the harmony binary, or compile the harmony binary using a rust docker container, if neither cargo or a container runtime is available, output a message explaining the situation
+        - Run the newly compiled binary. (Ideally using pid handoff like exec does but some research around this should be done. I think handing off the process is to help with OS interaction such as terminal apps, signals, exit codes, process handling, etc but there might be some side effects)
+    - If not
+        - Suggest initializing a project by auto detecting what the project looks like
+        - When the project type cannot be auto detected, provide links to Harmony's documentation on how to set up a project, a link to the examples folder, and a ask the user if he wants to initialize an empty Harmony project in the current folder
+            - harmony/Cargo.toml with dependencies set
+            - harmony/src/main.rs with an example LAMPScore setup and ready to run
+- This same binary can be used in a CI environment to run the target project's Harmony module. By default, we provide these opinionated steps :
+    1. **An empty check step.** The purpose of this step is to run all tests and checks against the codebase. For complex projects this could involve a very complex pipeline of test environments setup and execution but this is out of scope for now. This is not handled by harmony. For projects with automatic setup, we can fill this step with something like `cargo fmt --check; cargo test; cargo build` but Harmony is not directly involved in the execution of this step.
+    2. **Package and publish.** Once all checks have passed, the production ready container is built and pushed to a registry. This is done by Harmony.
+    3. **Deploy to staging automatically.** 
+    4. **Run a sanity check on staging.** As Harmony is responsible for deploying, Harmony should have all the knowledge of how to perform a sanity check on the staging environment. This will, most of the time, be a simple verification of the kubernetes health of all deployed components, and a poke on the public endpoint when there is one.
+    5. **Deploy to production automatically.** Many projects will require manual approval here, this can be easily set up in the CI afterwards, but our opinion is that 
+    6. **Run a sanity check on production.** Same check as staging, but on production.
+
+*Note on providing a base pipeline :* Having a complete pipeline set up automatically will encourage development teams to build upon these by adding tests where they belong. The goal here is to provide an opiniated solution that works for most small and large projects. Of course, many orgnizations will need to add steps such as deploying to sandbox environments, requiring more advanced approvals, more complex publication and coordination with other projects. But this here encompasses the basics required to build and deploy software reliably at any scale.
+
+### Environment setup
+
+TBD : For now, environments (tenants) will be set up and configured manually. Harmony will rely on the kubeconfig provided in the environment where it is running to deploy in the namespace.
+
+For the CD tool such as Argo or Flux they will be activated by default by Harmony when using application level Scores such as LAMPScore in a similar way that the container is automatically built. Then, CI deployment steps will be notifying the CD tool using its API of the new release to deploy.

+# Architecture Decision Record: Monitoring Notifications
+
+Initial Author: Taha Hawa
+
+Initial Date: 2025-06-26
+
+Last Updated Date: 2025-06-26
+
+## Status
+
+Proposed
+
+## Context
+
+We need to send notifications (typically from AlertManager/Prometheus) and we need to receive said notifications on mobile devices for sure in some way, whether it's push messages, SMS, phone call, email, etc or all of the above.
+
+## Decision
+
+We should go with https://ntfy.sh except host it ourselves.
+
+`ntfy` is an open source solution written in Go that has the features we need.
+
+## Rationale
+
+`ntfy` has pretty much everything we need (push notifications, email forwarding, receives via webhook), and nothing/not much we don't. Good fit, lightweight.
+
+## Consequences
+
+Pros:
+
+- topics, with ACLs
+- lightweight
+- reliable
+- easy to configure
+- mobile app
+  - the mobile app can listen via websocket, poll, or receive via Firebase/GCM on Android, or similar on iOS.
+- Forward to email
+- Text-to-Speech phone call messages using Twilio integration
+- Operates based on simple HTTP requests/Webhooks, easily usable via AlertManager
+
+Cons:
+
+- No SMS pushes
+- SQLite DB, makes it harder to HA/scale
+
+## Alternatives considered
+
+[AWS SNS](https://aws.amazon.com/sns/):
+Pros:
+
+- highly reliable
+- no hosting needed
+
+Cons:
+
+- no control, not self hosted
+- costs (per usage)
+
+[Apprise](https://github.com/caronc/apprise):
+Pros:
+
+- Way more ways of sending notifications
+- Can use ntfy as one of the backends/ways of sending
+
+Cons:
+
+- Way too overkill for what we need in terms of features
+
+[Gotify](https://github.com/gotify/server):
+Pros:
+
+- simple, lightweight, golang, etc
+
+Cons:
+
+- Pushes topics are per-user

+# 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."
