+# Configuration Layout
+
+This repository keeps environment-specific infrastructure configuration under the `config/` directory. The layout follows a consistent project → environment → cloud/provider → resource-module hierarchy so that each stack can be managed independently.
+
+## Recommended standard layout
+
+```
+config/
+└── <project>/
+    └── <env>/
+        └── <cloud>/
+            ├── base.yaml
+            ├── identity.yaml
+            ├── network.yaml
+            ├── security.yaml
+            ├── storage.yaml
+            ├── compute.yaml
+            ├── observability.yaml
+            └── <feature>.yaml
+```
+
+- **Project**: top-level application or platform (for example `modern-container-app`, `cloudneutral-platform`, or `ai-infra-lab`).
+- **Environment**: fully isolated deployment stages such as `dev`, `sit`, `uat`, and `prod`.
+- **Cloud/Provider**: clear provider identifiers such as `aws-cloud`, `gcp-cloud`, or `vultr-vps`.
+- **Resource modules**: YAML slices for base settings, identity, network, security, storage, compute, observability, and feature-specific needs.
+
+## Applied layout for this repository
+
+The current repo uses the `xzerolab` project with a `sit` environment. Provider-specific configurations are organized per cloud alongside shared assets for future environments.
+
+```

+            └── resources/
+                └── .gitkeep
+```
+
+Use this layout to keep each environment and provider self-contained, making it easy for CI/CD workflows to target the exact configuration needed for a deployment.
