+Thank you for installing myapp-chart.
+
+This chart packages all Kubernetes manifests from the original deployment directory and parameterizes environment, database name (with optional PR suffix), image, and domain for external access.
+
+Namespaces per developer (important):
+- Install each developer's environment into their own namespace using Helm's -n/--namespace flag.
+- No hardcoded namespace is used in templates; resources are created in .Release.Namespace.
+- Example namespaces: dev-alice, dev-bob, pr-123, etc.
+
+Key values:
+- deployment -> used as Database CR name and DB username (MARIADB_DB and MARIADB_USER)
+- image.repository/tag or image.digest -> container image
+- domain -> public FQDN used by TunnelBinding (required to expose app)
+- app/worker names, replicas, ports
+
+Examples:
+- Dev install (Alice):
+  helm upgrade --install myapp ./7project/charts/myapp-chart \
+    -n dev-alice --create-namespace \
+    -f values-dev.yaml \
+    --set domain=alice.demo.example.com \
+    --set-string rabbitmq.password="$RABBITMQ_PASSWORD" \
+    --set-string database.password="$DB_PASSWORD"
+
+- Dev install (Bob):
+  helm upgrade --install myapp ./7project/charts/myapp-chart \
+    -n dev-bob --create-namespace \
+    -f values-dev.yaml \
+    --set domain=bob.demo.example.com
+
+- Prod install (different cleanupPolicy):
+  helm upgrade --install myapp ./7project/charts/myapp-chart \
+    -n prod --create-namespace \
+    -f values-prod.yaml \
+    --set domain=app.example.com
+
+- PR (preview) install with DB name containing PR number (also its own namespace):
+  PR=123
+  helm upgrade --install myapp-pr-$PR ./7project/charts/myapp-chart \
+    -n pr-$PR --create-namespace \
+    -f values-dev.yaml \
+    --set prNumber=$PR \
+    --set deployment=preview-$PR \
+    --set domain=pr-$PR.example.com
+
+- Use a custom deployment identifier to suffix DB name, DB username and Secret name:
+  helm upgrade --install myapp ./7project/charts/myapp-chart \
+    -n dev-alice --create-namespace \
+    -f values-dev.yaml \
+    --set deployment=alice \
+    --set domain=alice.demo.example.com
+
+Render locally (dry run):
+  helm template ./7project/charts/myapp-chart -f values-dev.yaml --set prNumber=456 --set deployment=test --set domain=demo.example.com --namespace dev-test | sed -n '/kind: Database/,$p' | head -n 30

+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
+
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
+
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
