It's a shame that the lecture materials haven't been updated enough to listen in 2023. I can't say that I would absolutely recommend it unless the instructor does a major renewal for the 2023 version. Even though it's a lecture aimed at NEST beginners, the process of writing code is quite omitted, As the instructor said, there are a lot of steps that you have to follow by looking at the lecture materials on GitHub, but the GitHub lecture materials haven't been updated properly. When I get stuck while listening to the lecture, I want to compare the code on GitHub to see what's wrong, but even if I clone the GitHub materials, it often doesn't work.
