    ```
-   git clone <TODO: PUBLIC REPO LINK>
-   ```
-   Once you have tested this on a local machine, you can [request a VM from IT](https://itss.nvidia.com/) and deploy it there so it can run all the time.
-   
-   Currently, we are using the internal gitlab repository, which can be downloaded using following command:
-   ```
-   git clone -b multimodal_oran https://gitlab-master.nvidia.com/sae-industry/telco/ai-workflows/rag/oran_chatbot.git

 ### Prompt Augmentation
-<!-- <TODO: We can update this section> -->
 Depending on the backend and model, you may need to modify the way in which you format your prompt and chat conversations to interact with the model. The current design considers each query independently. However, if you put the input as a set of user/assistant/user interactions, you can combine multi-turn conversations. This may also require periodic summarization of past context to ensure the chat does not exceed the context length of the model.

 ### Multimodal Parsing:
 Upgrade the current PyMuPDF-based PDF parsing with a more sophisticated parser for improved extraction of images and tables. Employ a high-quality Multimodal Language Model (MLLM) to enhance image descriptions and implement structured data analysis techniques like text2sql or text2pandas for efficient table summarization.
