Hello, ssebong777. First, I would like to apologize for disappointing you by not meeting your expectations. I fully understand the point you raised. Especially from the perspective of someone learning new content for the first time, it could feel like the material is simply being read from English documentation, which I imagine was frustrating for you. However, this course was designed for developers who will actually be working directly with global documentation and development environments, rather than for absolute beginners. Therefore, I structured it to read through the official Anthropic documentation based on the original text as much as possible and explain what it means in a real-world professional context. The PPT is also intended more as a resource for interpreting the official documentation from a practical perspective rather than being a simple summary. In particular, as the course progresses toward the latter half, there is more content related to practical application rather than just document explanation, so if possible, I would appreciate it if you could check out at least the later sections.
