-### Using Neo4J for Storage

-```python
-export NEO4J_URI="neo4j://localhost:7687"
-export NEO4J_USERNAME="neo4j"
-export NEO4J_PASSWORD="password"

-When you launch the project be sure to override the default KG: NetworkS

 ### Increasing context size
 In order for LightRAG to work context should be at least 32k tokens. By default Ollama models have context size of 8k. You can achieve this using one of two ways:
