+## Build with Android Studio
+
+Import the `examples/llama.android` directory into Android Studio, then perform a Gradle sync and build the project.
+![Project imported into Android Studio](./android/imported-into-android-studio.png)
+
+This Android binding supports hardware acceleration up to `SME2` for **Arm** and `AMX` for **x86-64** CPUs on Android and ChromeOS devices.
+It automatically detects the host's hardware to load compatible kernels. As a result, it runs seamlessly on both the latest premium devices and older devices that may lack modern CPU features or have limited RAM, without requiring any manual configuration.
+
+A minimal Android app frontend is included to showcase the binding’s core functionalities:
+1.	**Parse GGUF metadata** via `GgufMetadataReader` from either a `ContentResolver` provided `Uri` or a local `File`.
+2.	**Obtain a `TierDetection` or `InferenceEngine`** instance through the high-level facade APIs.
+3.	**Send a raw user prompt** for automatic template formatting, prefill, and decoding. Then collect the generated tokens in a Kotlin `Flow`.
+
+For a production-ready experience that leverages advanced features such as system prompts and benchmarks, check out [Arm AI Chat](https://play.google.com/store/apps/details?id=com.arm.aichat) on Google Play.
+This project is made possible through a collaborative effort by Arm's **CT-ML**, **CE-ML** and **STE** groups:

 ## Build on Android using Termux
 
 [Termux](https://termux.dev/en/) is an Android terminal emulator and Linux environment app (no root required). As of writing, Termux is available experimentally in the Google Play Store; otherwise, it may be obtained directly from the project repo or on F-Droid.

+ * This class implements a singleton pattern for managing the lifecycle of a single LLM instance.

+ * with the underlying C++ native code.
+ *
+ * The typical usage flow is:
+ * 1. Get instance via [getInstance]
+ * 2. Load a model with [loadModel]
+ * 3. Send prompts with [sendUserPrompt]
+ * 4. Generate responses as token streams
+ * 5. Perform [cleanUp] when done with a model
+ * 6. Properly [destroy] when completely done
+ *
+ * State transitions are managed automatically and validated at each operation.
