-## Usage
-Import into your consuming module (Eg: AppModule):
+### Importing
+This library ships with [standalone components](https://angular.dev/reference/migrations/standalone)
+
+How you consume it depends on whether you have migrated to standalone components (the default since Angular v19)
+
+#### Standalone Component
+
+Add the `QrCodeComponent` or `QrCodeDirective` to your `@Component` declarations `imports` array. Eg:
+```typescript
+import { QrCodeComponent } from 'ng-qrcode';
+
+@Component({
+  selector: "app-root",
+  templateUrl: "./app.component.html",
+  styleUrls: ["./app.component.scss"],
+  standalone: true,
+  imports: [
+    QrCodeComponent,
+  ]
+})
+export class AppComponent {
+  // ...
+}
+```
+#### NgModule
 
+If you're still using `NgModule` / non-standalone components, then you can add `QrCodeComponent` or `QrCodeDirective` to your `@NgModule` declarations `imports` array. Eg:
 ```typescript
-import { QrCodeModule } from 'ng-qrcode';
+import { QrCodeComponent } from 'ng-qrcode';
 
 @NgModule({
   imports: [
-    QrCodeModule
+    QrCodeComponent
   ]
 })
 ```
 
+## Usage
+
 ### Component
 ```angular17html
 <qr-code value="Hello world!"
