+# Firebase AI Logic quickstart sample app
+
+This Android sample app demonstrates how to use state-of-the-art
+generative AI models (like Gemini) to build AI-powered features and applications.
+For more information about Firebase AI Logic, visit the [documentation](http://firebase.google.com/docs/ai-logic).
+
+## Getting Started
+
+To try out this sample app, you need to use latest stable version of Android Studio.
+However, if you want to latest lint checks and AI productivity features in Android
+Studio use the latest preview version of [Android Studio](https://developer.android.com/studio/preview).
+
+## Features
+
+There are 2 main files that demonstrate the use of Firebase AI Logic:
+
+- [ChatViewModel.kt](app/src/main/java/com/google/firebase/quickstart/ai/feature/text/ChatViewModel.kt)
+ which can do things such as:
+    -  [Generate Text](https://firebase.google.com/docs/ai-logic/generate-text)
+    -  [Generate structured output (JSON)](https://firebase.google.com/docs/ai-logic/generate-structured-output)
+    -  [Analyze images](https://firebase.google.com/docs/ai-logic/analyze-images)
+    -  [Analyze video](https://firebase.google.com/docs/ai-logic/analyze-video)
+    -  [Analyze audio](https://firebase.google.com/docs/ai-logic/analyze-audio)
+    -  [Analyze documents (PDFs)](https://firebase.google.com/docs/ai-logic/analyze-documents)
+    -  [Generate images using Gemini 2.0](https://firebase.google.com/docs/ai-logic/generate-images-imagen)
+- [ImagenViewModel](app/src/main/java/com/google/firebase/quickstart/ai/feature/media/imagen/ImagenViewModel.kt)
+ which shows how to [Generate images using Imagen models](https://firebase.google.com/docs/ai-logic/generate-images-imagen)
+
+## All samples
+
+The full list of available samples can be found in the
+[FirebaseAISamples.kt file](app/src/main/java/com/google/firebase/quickstart/ai/FirebaseAISamples.kt).
