+# Get Started with Microsoft Agent Framework Azure AI Search
+
+Please install this package via pip:
+
+```bash
+pip install agent-framework-aisearch --pre
+```
+
+## Azure AI Search Integration
+
+The Azure AI Search integration provides context providers for RAG (Retrieval Augmented Generation) capabilities with two modes:
+
+- **Semantic Mode**: Fast hybrid search (vector + keyword) with semantic ranking
+- **Agentic Mode**: Multi-hop reasoning using Knowledge Bases for complex queries
+
+### Basic Usage Example
+
+See the [Azure AI Search context provider examples](https://github.com/microsoft/agent-framework/tree/main/python/samples/getting_started/agents/azure_ai/) which demonstrate:
+
+- Semantic search with hybrid (vector + keyword) queries
+- Agentic mode with Knowledge Bases for complex multi-hop reasoning
+- Environment variable configuration with Settings class
+- API key and managed identity authentication
