+
+## Dependency Injection
+
+As a prerequisite, ensure that `AngularFire` has been added to your project via
+```bash
+ng add @angular/fire
+```
+
+Provide a Vertex AI instance in the application's `app.config.ts`:
+
+```ts
+import { provideFirebaseApp, initializeApp } from '@angular/fire/app';
+import { provideVertexAI, getVertexAI } from '@angular/fire/vertexai-preview';
+
+export const appConfig: ApplicationConfig = {
+  providers: [
+    provideFirebaseApp(() => initializeApp({ ... })),
+    provideVertexAI(() => getVertexAI()),
+    ...
+  ],
+  ...,
+}
+```
+
+Next inject `VertexAI` into your component:
+
+```typescript
+import { Component, inject } from '@angular/core';
+import { VertexAI } from '@angular/fire/vertexai-preview';
+
+@Component({ ... })
+export class MyComponent {
+    private vertexAI = inject(VertexAI);
+    ...
+}
+```
+
+## Firebase API
+
+AngularFire wraps the Firebase JS SDK to ensure proper functionality in Angular, while providing the same API.
+
+Update the imports from `import { ... } from 'firebase/vertexai-preview'` to `import { ... } from '@angular/fire/vertexai-preview'` and follow the official documentation.
