+## LlamaIndex data framework
+
+LlamaIndex is an open source is a data framework for building Large Language Models (LLMs) based application. To get started, you'll need to install the LlamaIndex and set up your API key.
+
+### Configuration
+
+To use the LlamaIndex framework with Scaleway's Generative APIs, first install the required dependencies:
+
+```bash
+    pip install llama-index-llms-openai-like
+```
+
+Then set the API key and base URL in your OpenAILike-compatible client:
+
+```python
+from llama_index.llms.openai_like import OpenAILike
+
+llm = OpenAILike(
+model="pixtral-12b-2409",
+api_key="<API secret key>",
+api_base="https://api.scaleway.ai/v1",
+max_tokens=512,
+temperature=0.7,
+top_p=1,
+presence_penalty=0,
+)
+```
+<Message type="tip">
+    Make sure to replace `<API secret key>` with your actual API key.
+</Message>
+
+### Using LlamaIndex client to chat with the LLM
+
+```python
+    response = llm.chat([ChatMessage("could you tell about Scaleway please")])
+    print(response)
+```
+
