+# Agent Framework Retrieval Augmented Generation (RAG) with Neo4j GraphRAG
+
+This sample demonstrates how to create and run an agent that uses the [Neo4j GraphRAG context provider](https://github.com/neo4j-labs/neo4j-maf-provider) with Microsoft Agent Framework for .NET.
+
+The sample uses a Neo4j fulltext index for retrieval and a Cypher `RetrievalQuery` to enrich results with related companies, products, and risk factors.
+
+## Prerequisites
+
+- .NET 10 SDK or later
+- Azure OpenAI endpoint and chat deployment
+- Azure CLI installed and authenticated
+- A Neo4j database with chunked documents and a fulltext index such as `search_chunks`
+
+## Environment variables
+
+```powershell
+$env:AZURE_OPENAI_ENDPOINT="https://your-resource.openai.azure.com/"
+$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-5.4-mini"
+$env:NEO4J_URI="neo4j+s://your-instance.databases.neo4j.io"
+$env:NEO4J_USERNAME="neo4j"
+$env:NEO4J_PASSWORD="your-password"
+$env:NEO4J_FULLTEXT_INDEX_NAME="search_chunks"
+```
+
+## Build and run
+
+```powershell
+dotnet build
+dotnet run --framework net10.0 --no-build
+```
+
+The sample issues a few questions against the graph-backed retrieval provider and prints the responses to the console.
