2. Add a Conversational Retrieval Chain: This allows for back-and-forth conversations and memory of previous interactions.
3. Connect the Chat Model: Add the “Chat Ollama” node and connect it to the chain. Use the model name you copied earlier.
4. Add Memory: Connect the “Buffer Memory” node to the chain so the chatbot remembers past conversations.
5. Connect the Vector Store: Add the “Document Store” node and select the document store you created earlier.

6. Test and Expand! 🚀
