 2. Launch tool services </br>
    In this example, we will use some of the mock APIs provided in the Meta CRAG KDD Challenge to demonstrate the benefits of gaining additional context from mock knowledge graphs.
 
-```
-docker run -d -p=8080:8000 docker.io/aicrowd/kdd-cup-24-crag-mock-api:v0

 4. Launch agent services</br>
    The configurations of the supervisor agent and the worker agent are defined in the docker-compose yaml file. We currently use openAI GPT-4o-mini as LLM, and we plan to add support for llama3.1-70B-instruct (served by TGI-Gaudi) in a subsequent release.
    To use openai llm, run command below.
 
-```
-cd docker/openai/
-bash launch_agent_service_openai.sh
-```
+   ```
+   cd docker/openai/
+   bash launch_agent_service_openai.sh

 DocRetriever are the most widely adopted use case for leveraging the different methodologies to match user query against a set of free-text records. DocRetriever is essential to RAG system, which bridges the knowledge gap by dynamically fetching relevant information from external sources, ensuring that responses generated remain factual and current. The core of this architecture are vector databases, which are instrumental in enabling efficient and semantic retrieval of information. These databases store data as vectors, allowing RAG to swiftly access the most pertinent documents or data points based on semantic similarity.
