+### Option 1: Full Console (ObjectStack Backend)
+
+Install the core packages to use `<SchemaRenderer>` inside your Next.js or Vite app with ObjectStack backend:
 
 ```bash
 npm install @object-ui/react @object-ui/components @object-ui/data-objectstack
 ```
 
+### Option 2: Minimal Integration (Any Backend) ⭐ **NEW!**
+
+Use ObjectUI components without the full console infrastructure. Perfect for integrating into existing apps:
+
+```bash
+npm install @object-ui/app-shell @object-ui/providers
+```
+
+Then build your own console in ~100 lines:
+```tsx
+import { AppShell, ObjectRenderer } from '@object-ui/app-shell';
+import { ThemeProvider, DataSourceProvider } from '@object-ui/providers';
+
+function MyConsole() {
+  return (
+    <ThemeProvider>
+      <DataSourceProvider dataSource={myAPI}>
+        <AppShell sidebar={<MySidebar />}>
+          <ObjectRenderer objectName="contact" />
+        </AppShell>
+      </DataSourceProvider>
+    </ThemeProvider>
+  );
+}
+```
+
+**Benefits:**
+- 🎯 **Lightweight**: ~50KB vs 500KB+ full console
+- 🔌 **Any Backend**: REST, GraphQL, custom APIs (not just ObjectStack)
+- 🎨 **Full Control**: Custom routing, auth, layouts
+- 📦 **Cherry-pick**: Use only what you need

+See [examples/minimal-console](examples/minimal-console) for a complete working example.
