-LightRAG supports integration with various frameworks and model providers through wrappers. These wrappers provide a consistent interface while abstracting away the specifics of each framework.
+LightRAG supports integration with LlamaIndex.
 
-### Current Wrappers
-
-1. **LlamaIndex** (`wrapper/llama_index_impl.py`):
+1. **LlamaIndex** (`llm/llama_index_impl.py`):
    - Integrates with OpenAI and other providers through LlamaIndex
-   - Supports both direct API access and proxy services like LiteLLM
-   - Provides consistent interfaces for embeddings and completions
-   - See [LlamaIndex Wrapper Documentation](lightrag/wrapper/Readme.md) for detailed setup and examples
+   - See [LlamaIndex Documentation](lightrag/llm/Readme.md) for detailed setup and examples
 
 ### Example Usage

 # Using LlamaIndex with direct OpenAI access
 from lightrag import LightRAG
