-This a test README just to appease the eval warnings if we don't have one
+!!! Danger "Experimental"
+    This service is for demonstration purpose only and may change in the future.
+
+The Hello-World Clan Service is a minimal example showing how to build and register your own service.
+
+It serves as a reference implementation and is used in clan-core CI tests to ensure compatibility.
+
+## What it demonstrates
+
+- How to define a basic Clan-compatible service.
+- How to structure your service for discovery and configuration.
+- How Clan services interact with nixos.
+
+## Testing
+
+This service demonstrates two levels of testing to ensure quality and stability across releases:
+
+1. **Unit & Integration Testing** — via [`nix-unit`](https://github.com/nix-community/nix-unit)
+2. **End-to-End Testing** — via **NixOS VM tests**, which we extended to support **container virtualization** for better performance.
+
+We highly advocate following the [Practical Testing Pyramid](https://martinfowler.com/articles/practical-test-pyramid.html):
+
+* Write **unit tests** for core logic and invariants.
+* Add **one or two end-to-end (E2E)** tests to confirm your service starts and behaves correctly in a real NixOS environment.
+
+NixOS is **untyped** and frequently changes; tests are the safest way to ensure long-term stability of services.
+
+```

+### nix-unit
+
+We highly advocate the usage of
+
+[nix-unit](https://github.com/nix-community/nix-unit)
+
+Example in: tests/eval-tests.nix
+
+If you use flake-parts you can use the [native integration](https://flake.parts/options/nix-unit.html)
+
+If nix-unit succeeds you'r nixos evaluation should be mostly correct.
+
+!!! Tip
+    - Ensure most used 'settings' and variants are tested.
+    - Think about some important edge-cases your system should handle.
+
+### NixOS VM / Container Test
+
+!!! Warning "Early Vars & clanTest"
+    The testing system around vars is experimental
+
+    `clanTest` is still experimental and enables container virtualization by default.
+    This is still early and might have some limitations.
+
+Some minimal boilerplate is needed to use `clanTest`
+
+```nix
+nixosLib = import (inputs.nixpkgs + "/nixos/lib") { }
+nixosLib.runTest (
+    { ... }:
