I really enjoyed your great lecture.

It was great to be able to immediately build a Jeju Island travel guide chatbot using the RAG, LangChain, and Streamlit workflow learned in the lecture. Since it was practice-oriented rather than theory-heavy, it was great that even a beginner could create a service and check the results right away.

I signed up because I need to handle automation tasks using n8n at work, but the difficulty level seems to be entirely for developers. I tried to follow along step-by-step during the practice, but you suddenly started coding a lot without explaining the concepts of those items, so I didn't know which parts to follow. I wish there were more specific explanations on why these items are used, but it seems too difficult for a non-developer to understand. However, I think the n8n concepts and agents you taught will be very useful.

I enjoyed the lecture. It was very helpful for grasping the concepts. However, there are two points I found a bit disappointing: 1. It seems necessary to update the content to the latest version. Many of the LangChain documentation sites shown during the lecture were difficult to find. 2. For future lecture recordings, I would appreciate it if you could check whether the practice codes work on Windows for the sake of Windows users. There were a few instances where they didn't work properly due to OS-related issues.
