 # ClusterCanvas
 
 A web-based dashboard for managing Proxmox VMs and LXC containers. After configuration it discovers hosts and shows per‑instance details like hostname, storage and RAM usage, and status. From the same interface you can view logs, run updates, deploy changes, and perform other routine maintenance tasks.
+
+## Layout
+
+| Path | Role |
+|------|------|
+| `service/` | Go HTTP API |
+| `webui/` | Vite + React + TypeScript SPA |
+
+## Prerequisites
+
+- Go 1.22+
+- Node.js 20+ and npm
+
+## Run
+
+Start the API (default `:8080`, override with `PORT`):
+
+```bash
+make service
+```
+
+Start the web UI (Vite on `:5173`, proxies `/health` and `/api` to the service):
+
+```bash
+make webui
+```
+
+Optional: set `VITE_API_BASE_URL` (defaults to `http://localhost:8080`) if you call the API without the Vite proxy.
+
+## Test
+
+```bash
+make test
+```
+
+This runs `go test ./...` in `service/` and Vitest in `webui/`.
+
+## Build
+
+```bash
+make build
+```
+
+Produces `bin/clustercanvas-server` and `webui/dist/`.

+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some Oxlint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
+
+## 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 Oxlint configuration
+
+If you are developing a production application, we recommend enabling type-aware lint rules by installing `oxlint-tsgolint` and editing `.oxlintrc.json`:
+
+```json
+{
+  "$schema": "./node_modules/oxlint/configuration_schema.json",
+  "plugins": ["react", "typescript", "oxc"],
+  "options": {
+    "typeAware": true
+  },
+  "rules": {
+    "react/rules-of-hooks": "error",
+    "react/only-export-components": ["warn", { "allowConstantExport": true }]
+  }
+}
+```
+
+See the [Oxlint rules documentation](https://oxc.rs/docs/guide/usage/linter/rules) for the full list of rules and categories.
