 The following steps are required to run an LLM task (i.e., Llama2) via the Android app.

 We need a pair of the model and tokenizer files for an LLM task. You can download a small model for the Android device using this [guide](https://github.com/karpathy/llama2.c/tree/master?tab=readme-ov-file#custom-tokenizers).

+#### Handling ML Computation Delegation Requests from the Android Components in the Other package
+
+The MLAgent can handle the delegation requests from the other package. The following code should be added to the other package's `AndroidManifest.xml`
+for [package visibility](https://developer.android.com/training/package-visibility/declaring).
+
+```xml
+<manifest xmlns:android="http://schemas.android.com/apk/res/android"
+    xmlns:tools="http://schemas.android.com/tools">
+    <queries>
+        <package android:name="ai.nnstreamer.ml.inference.offloading" />
+        <package android:name="ai.nnstreamer.ml.inference.offloading.MainService" />
+    </queries>
+    ...
+</manifest>
+```
+
+We are providing a simple example application that demonstrates this scenario. This example sends an input prompt to the MLAgent
+and retrieves the generated output text using the llama2 model.
+
+To receive auto-generated text by llama2 model, 1) enter the beginning of the sentence and 2) press the `Run llama2` button.
