Hello Toby. I enjoyed the lecture. Previously, I only knew that Spring Boot was just to make Spring easier to use, but while listening to the lecture, I learned how Boot's auto-configuration is processed and what's in the auto-configuration list. After listening to the lecture, I felt that rather than just how Boot's auto-configuration is done, I could understand Spring with this auto-configuration information, and that if I started looking for auto-configuration information, I could find an entry point to understand the technology. I've tried to open Spring's internal code a few times before, but Spring is so vast and there was no direction in how I looked for it. Now, I think I can look for it with direction. Thank you for the great lecture.
