+# Creating an AIAgent with Google Gemini
+
+This sample demonstrates how to create an AIAgent using Google Gemini models as the underlying inference service.
+
+The sample showcases two different `IChatClient` implementations:
+
+1. **Google GenAI** - Using the official [Google.GenAI](https://www.nuget.org/packages/Google.GenAI) package
+2. **Mscc.GenerativeAI.Microsoft** - Using the community-driven [Mscc.GenerativeAI.Microsoft](https://www.nuget.org/packages/Mscc.GenerativeAI.Microsoft) package
+
+## Prerequisites
+
+Before you begin, ensure you have the following prerequisites:
+
+- .NET 10.0 SDK or later
+- Google AI Studio API key (get one at [Google AI Studio](https://aistudio.google.com/apikey))
+
+Set the following environment variables:
+
+```powershell
+$env:GOOGLE_GENAI_API_KEY="your-google-api-key"  # Replace with your Google AI Studio API key
+$env:GOOGLE_GENAI_MODEL="gemini-2.5-fast"  # Optional, defaults to gemini-2.5-fast
+```
+
+## Package Options
+
+### Google GenAI (Official)
+
+The official Google GenAI package provides direct access to Google's Generative AI models. This sample uses the `AsIChatClient()` extension method to convert the Google client to an `IChatClient`.
+
+### Mscc.GenerativeAI.Microsoft (Community)
+
+The community-driven Mscc.GenerativeAI.Microsoft package provides a ready-to-use `IChatClient` implementation for Google Gemini models through the `GeminiChatClient` class.
